https://www.newegg.com/Product/Product.aspx?Item=N82E16811112040
i got that weblink from my newegg-order-history, lian-li.com pc-65-b can not be searched in newegg anymore.
pros : 1. lian-li pc-65b is lightweight because lian-li.com pc-65-b is made from aluminum
2. comes with harddisk-fan which cool-down harddisk.
antec.com->300 does not come with harddisk-fan. [source:'antec.com' in https://en.wikipedia.org/wiki/Antec]
harddisk-fan is more important than case-roof-fan because harddisk gets hot without fan.
many-air-holes on case-roof without case-roof-fan, is ok.
many-air-holes on case-roof is important because heat should rise automatically.
not having rear-case-fan seems ok.
rear-case-fan maybe evacuate cool-air and hot-air.
i want cool-air to stay inside computer-case.
3. thumb-screw for harddisk
cons : 1. easily scratched
2. motherboard-tray seems redundant, add more complexity.
i accidentally pinch power-cable between motherboard-tray and inner-case-wall
then windows-xp restart by itself randomly.
memtest86 says memory is fine
then later i realise power-cable is being pinched between motherboard-tray and inner-case-wall.
3. fan-size is 80mm, less than 120mm but 2 80mm fans blowing harddisk so airflow to harddisk's hotspots maybe is as good or better.
but more fan makes more noise but lian-li.com pc-65-b comes with fan installed
not like antec.com->300 needing additional effort for installing fan.
some fan specs (cfm means airflow):
vantec 120mm 1500rpm 53cfm
92mm 1750rpm 28cfm
80mm 2050rpm 27cfm
60mm 2600rpm 12cfm
rosewill 80mm 2500rpm 33.21cfm

4. lian-li.com pc-65-b has air-filter in front-panel.
air-filter block dust and hinder air-flow. i want maximum air-flow, i can tolerate dust.
that air-filter can be removed.
5. expensive
reason i sell this computer in craigslist : [25 sep 2018 7:17 pm edt | 7:33 pm edt add 'i was trying to follow :' | 7:50 pm edt add 'now i realise i must not forget old component which made me survive.' | add 'but bible has flaw' | 11:25 pm edt add 'and maybe that computer is akujiki.' | 11:48 pm edt add 'maybe computer-case with black color makes user feels superstitious.' | 11:51 pm edt add 'but opening side-panel-door shows interior-computer-case color which is not black.' | 12:30 am edt add 'seeing a cat with black color, can make ppl feel superstitious']
1. i was trying to follow :
'Marrying a Woman Taken Prisoner in War
Moses said to Israel:
10 From time to time, you men will serve as soldiers and go off to war.
The Lord your God will help you defeat your enemies, and
you will take many prisoners. 11-13 One of these prisoners may be
a beautiful woman, and you may want to marry her. But first you must bring her
into your home, and have her shave her head, cut her nails, get rid of her
foreign clothes, and start wearing Israelite clothes. She will mourn a month
for her father and mother, then you can marry her.' in
https://www.biblegateway.com/passage/?search=Deuteronomy+21&version=CEV
then i realise dell's motherboard (american), foxconn, made in china,
is foreign as well.
now i realise i must not forget old component which kept me alive
during that difficult-time.
2. i try to follow :
'during that year, and when they have all they want from your fields,
leave the rest for wild animals.' in http://wortel.ucoz.com/7years.htm
3. i had bad memory during working with that computer.
maybe by selling that computer, i won't see that computer so my bad
memory during working with that computer, disappears.
but now i realise bad memory can become a lesson for the future.
and i was trying to avoid seeing that computer for a while, while
i rejuvenate my mental-strength. then now i can say
'i realise bad memory can become a lesson for the future'
but now i realise bible has flaw : http://wortel.ucoz.com/bible_flaw.htm
and everytime new computer-component is being made, maybe
iron-miner blows soil with dynamite, killing beneficial earthworm
to get more iron.
https://www.youtube.com/watch?v=7fEJcyMNfII
(iron mine's good explosion and bad explosion compilation)
and maybe that computer is akujiki.
akujiki is a blade which wants to be used
source :
'If the blade's hunger is left unsatisfied,
it will slowly devour its owner's life force. Thus, whosoever
uses Akujiki shall forever be cursed with an unfortunate fate;
in order to sustain the blade's hunger, those who wield Akujiki
must dedicate their entire lives to the slaughter of any and
all beings that possess Yin, and then they must be devoured in
their last moments.'

maybe computer-case with black color makes user feels superstitious.
but opening computer-case-side-panel-door shows computer-case-interior color
which is not black.
i did not open that computer's side-panel-door during using that computer.
seeing a cat with black color, can make ppl feel superstitious

review for asus-p8h61-m le :
cons : 1. in a tower-computer-case :
there are 2 harddisk sata-connectors on motherboard which
enforce 2 sata-cable-connectors to face downward,
making 2 release-buttons on those 2 sata-cable-connector
face downward.
so it is impossible to see that downward-facing-release-button
without ducking.
so i can forget there is a release-button which
must be pressed prior unplugging sata-cable-connector.
there are other 2 harddisk sata-connectors on motherboard
which face upward.
somehow i used 2 downward-facing-harddisk-connectors.
i should have used 2 upward-facing-harddisk-connectors.
2. takes more than 1 mouse click to shutdown 1 cpu core in bios.
because i always shutdown 1 cpu core in bios to save electricity.
pros : no other complain.
suggestion :
1)maybe if cmos battery is not on motherboard then
show qestion in console asking
how many cpu core should be turned on ? ('1'/'a' for all/[number]/'b' for enter 'bios')
enter today's date and timezone : 12 oct 2018 5:1 pm
so mouse-click-action is reduced.
2)put usb-memory inside motherboard to remember user-selection without cmos-battery?
this idea come during i read https://en.wikipedia.org/wiki/Fujio_Masuoka from 'Fujio Masuoka' in https://en.wikipedia.org/wiki/Flash_memory from https://global.honda/newsroom/news/2018/c180928beng.html from https://global.honda/newsroom/?year=2018&page=3 result 2
but usb-memory maybe is not worth installing because motherboard-clock still need cmos-battery.
why i choose celeron-g540 ?
that is 2nd cheapest celeron.
the cheapest celeron has 2.4 ghz speed,
chinese fairy tale says 4 brings bad luck because
4 in chinese language is a homonym, has 2 meanings :

16 january 2017 :
bought fan brand insignia from bestbuy,
http://www.bestbuy.com/site/insignia-120mm-case-cooling-fan-black/3648006.p?skuId=3648006,
to be installed in the front of antec.com->300 to
cool down harddrive
but power cable of insignia fan, is too short,
can not reach cha_fan socket on mobo.
the insignia fan lay on the floor, not used.
bought 6 inches extension power cable from
molex power source to 3 x 4 pin fan cables
in newegg.
that 6 inches extension cable provide power to
3 fans.
21 january 2017 :
while waiting 6 inches extension power cable
from newegg, i had idea to replace rear fan in antec.com->300
with insignia fan bought from bestbuy,
http://www.bestbuy.com/site/insignia-120mm-case-cooling-fan-black/3648006.p?skuId=3648006
, made that rear insignia fan move air to interior
instead of move air to exterior,
providing fresh air to cpu.
the original antec.com->300 rear fan is now installed in the front
of antec.com->300, move resh air to interior
to cool down harddrive installed
in harddrive cage level 2.
all side panels, front panel, metal slots expansion
cover of antec.com->300, was
removed to cool down components further, because
psu location in antec.com->300, suck fresh air from above,
and above is where cpu is located, so psu maybe
trying to grab fresh air designated to cool down
cpu.
9 feb 2017
10:52 am :
last night i was browsing computer case in newegg.com
then i realised my antec.com->300 can have 120mm fan
on side panel, moving air to interior for psu.
11:09 am :
but i realised asus micro atx P8H61M LE
lacks extra cha_fan socket to provide power to
120mm fan on side panel.
asus micro atx P8H61M LE has only 1 cha_fan
on the left side of cpu, and that is being used
by insignia rear fan 120mm,

can not fit the 4 pin power cable in insignia fan which
was bought from bestbuy
i can not find a 120mm fan with power cable eating
power directly on molex cable from psu.
i doubt 3-pin to molex adapter provided by
http://store.antec.com/enclosure-fans/truequiet-120-red.html#
can fit the power cable fan
11:43 am
i realised what i bought from newegg.com is 3 pin to molex
adapter
https://www.newegg.com/Product/Product.aspx?Item=9SIABU94WV1658&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel-_-Content-_-text-_-
and 3 pin to molex adapter can not make 4 pin insignia fan
cable connect to molex.
the 4 pin cable in insignia fan can not fit 3 pin in
3 pin to molex adapter from newegg.com.
but product description says 4-pin, 3-pin, i thought
3-pin and 4-pin are compatible, apparently not compatible :
'6 inch IDE Molex 4-pin to Case cooling Fan 3-pin TX3 Multi-Fan Out Power Adapter Converter Cable w/ Speed Reduction ,2x5V/2x12V '

stripped the screw for fan on top panel of antec.com->300.
reverse the wind direction for fan on top panel,
the fan move air to interior, instead of to exterior,
pushing air to cpu area, psu.
when tightening the last screw, the drill slips
then strips the screw. now the screw stuck on the fan.
next time i must pre-drill the fan with the
fan laying on the floor, prior mounting
the fan to computer case.

bought screw #10 x 1/2 inches hex head slotted made by
everbilt in homedepot.
newegg reviewer says slotted head is harder to break
than phillips head.
source :

apparently the everbilt screw can drill the
fan and hold the fan to antec.com->300.
but the everbilt screw protrude from top panel.
because the hex head of the everbilt screw is bigger
than original screw from antec.com->300.
slotted head is intended to be used by human.
phillip head is intended to be used by machine.
source :
1. 'Phillips heads exist because the flat head
does very poorly when you have a machine
turning the screws. These machines tend to
be very powerful and the flat head screws
would get over tightened and break. So the
Phillips was designed so that the bit would
slip out if it reached that point. The down
side is that this "feature" works fairly
shitty when it's a human doing the work by
hand or using a low power consumer drill.'

from
google (slotted head harder to strip than phillip head) result 6
2. 'The Phillips screwdriver was invented in
Portland, Oregon in the late 1920s by Henry
Phillips in an effort to facilitate the
installation of screws using power screw
drivers in an industrial setting. His design
addressed several drawbacks to slotted
screwdrivers, the most common type of
screwdriver at that time. One of these
drawbacks was the tendency of slotted drivers
to over-torque a screw. The Phillips
screwdriver was designed to purposely
pull-away or "cam-out" when the torque
becomes too great. This prevents the screw
head from snapping off and also allows the
operator to know when the screw is fully
seated. Early power screwdrivers did not
have torque limiters so cam-out was a
decided advantage of the Phillips screwdriver.'.
'Other advantages of the Phillips screwdriver
over the slotted screwdriver:
1) it is easier to seat the bit into the
screw head, and
2) it is easier to keep the bit in place
once it's seated (slotted screwdrivers
have a tendency to slide out of the
screw due to centrifugal force).'

stanley 10 pc MultiBit Ratcheting Screwdriver
http://www.stanleytools.com/en-us/products/automotive-tools/screwdrivers/phillips-pocket-standard/10-pc-multibit-ratcheting-screwdriver/68-010#reviews
with phillip tip,
is the screwdriver which destroyed the head of the phillip screw
which attach 140mm fan to top panel of antec.com->300.
the story is :
my hand was grabbing the handle
of that stanley screwdriver, the screwdriver tip has been
inserted to the screw, when i begin to twist my hand to twist
the screwdriver clockwise or counterclockwise, the handle
twist but the shank of the screwdriver does not
twist immediately, after i twist my hand a lot then
the shank begin to twist.
so twisting the handle of that screwdriver, a little, will not
twist the shank of that screwdriver.
twisting the handle a lot will twist the shank of that screwdriver.
so the shank has a delay when responding
to the twisting of the handle.
i set that screwdriver to neutral transmission
when using that.
but i feel setting that screwdriver to clockwise
or counterclockwise transmission, does not
eliminate delay between twisting the handle
and twisting the shank.
next time i will use old fashioned screwdriver.

https://www.youtube.com/watch?v=L41UdAf1VuA&t=7m7s
if top fan is turned off then only hot air
should rise because physics says hot air rise,
cool air descend.
maybe turning on top fan is bad idea because
cool air should stay inside the case, hot air
should rise exit the case.
rear fan still blow air to cpu, and should
push warm residue air from cpu, away from cpu.
psu maybe gets occasional warm residue air
from harddrive fan.

i meant initially top fan was pushing air
to psu, now i turned off top fan and
cpu temp remained ok as described above.

i have done the above long time ago then
smelled plastic odor sometimes.
i smell that same plastic odor again sometimes.
i smell that plastic odor as i am located 1/2 meter
away from antec.com->300. but my nose can not smell
that plastic odor inside antec.com->300.
the plastic odor is not intense and not always
can be smelled.
maybe that smell came from dust inside psu, i opened,
cleaned that psu 15 jan 2017 afternoon,
but i did not remove psu cicuit board from psu housing
because removing psu circuit board from psu housing
need to remove psu cable from small hole in psu cover,
i fear about detaching psu cable accidentally then
not knowing how to reattach psu cable.
reassembling psu cover was difficult.
paintbrush was used to sweep dust away from
psu circuit board then i blew dust away with air from
my mouth while closing my eyes, blew dust toward bathtub

for long-term stability. (This should not be confused with
conventional phase change pads that are pre-attached to many
heatsinks. Those pads melt each time they get hot then
re-solidify when they cool. The viscosity changes that
Arctic Silver 5 goes through are much more subtle and

'it can only sustain a finite number of writes before it dies.
There is a lot of science that goes into explaining why this
happens, but suffice it to say that as the SSD is used, the
electrical charges within cells must be periodically reset.
Unfortunately, the electrical resistance increases slightly
with every reset, which increases the voltage necessary
to write into a cell. Eventually, the required voltage
becomes so high that the particular cell becomes essentially
useless. Thus, a finite number of writes'

metal computer case side panel is more protective for transport.
computer case side panel should be removed when that computer
is not being transported,
to allow more air to cool down the interior of computer case.
aluminium case is easily scratched but lightweight, does not
induce wood fatigue, metal fatigue on building pillars.

25 june 2017 maybe between 3 pm to 5 pm,
i tried to remove heat sink from
dell's motherboard for dell dimension 8250
but failed.
i succeed using a wrench to destroy
4 plastic screws tips, those 4 tips
stick out underneath
dimension 8250 motherboard tray,
those 4 screw tips looks like a cone
which can shrink to
penetrate motherboard tray then
the screw tips cone enlarge
so the screw tips can not
be pulled out from motherboard
tray,
so i destroy those 4 screw tips cones
by grabbing those 4 screw tips using
a wrench then twist the wrench repeatedly.
destroying those 4 screw tips makes
those 4 screw tips cones
thin enough to fit the screw hole and
can be pulled out from motherboard
tray.
then i fail using a wrench
to push those 4 plastic screws tips
to unplug those 4 plastic screws
from the heat sink.
maybe 11 or 12 or 13 october 2017 (dog month),
around 7:30 pm est (dog hour),
i succeed using a flat head screwdriver
to wedge away those 4 plastic screws,
to unplug those 4 plastic screws
from the heat sink.
then i remove the heat sink from
dimension 8250 motherboard.
those 4 plastic screws have a screw head
which is smooth,
does not have 'slotted recessed drive',
does not have 'phillips recessed drive',
rather flexible,
can be destroyed rather easily.
if a screw head
is destroyed then
removing that headless screw
would be more difficult,
i stick a flat head screwdriver
below that screw head then
twist that flat head screwdriver
clockwise, counterclockwise repeatedly
to push away that screw head from
the heat sink.

year 2007 i bought 2 laptops 1 for deborah, 1 for my father,
custom ordered from lenovo website.
x60 models, 1 for deborah still works,
the other x60 for my father broke after 1.5 years, the warranty
is 1 year.
maybe the motherboard broke, that x60 could not boot,
only shows black screen.
lenovo technician willing to repair that x60 for
maybe 600 usd maximum. i did not repair that x60 laptop.
i check the maximum repair cost is 700 usd now.

july 2017, ram month :
i broke my dell-dimension-8250's harddisk.
harddisk model is western-digital wd-caviar wd1200.
i ran that dell-dimension-8250 without its case.
i discard that dell-dimension-8250-case after event
https://www.facebook.com/arnon.jaya/posts/10158956867010441?__xts__%5B0%5D=68.ARAEpWyRbr7WlkTX7c27kYKQPYhBdWkE2S-naWqMW8i1LFMiok__3qi7G7vQtkUY7B9xL8YzytFxrZuGbL1i8sx_h0UEMKyRLIWumLYwsJtbE2Nk5pBMAGWbmIC2-zUDqsFDWnYd519h&__tn__=-R
i don't know
whether republic-garbage-collector
https://www.republicservices.com/all-in-one-recycling?tab=local
from google (republic trash recycling)
recycle that case or not.
dell-dimension-8250 motherboard is foxconn-motherboard.
dell-dimension-8250 has motherboard-tray for
that foxconn-motherboard.
i thought that motherboard-tray can become open-air-case
but no...
because a stand-alone-video-card has a metal-plate for connector for
vga-cable, that metal-plate-connector will go below
that motherboard-tray, trying to puncture floor
where that motherboard-tray sits.
i tried putting that motherboard-tray above a
cardboard, then i put that harddisk above
a cardboard as well
because of harddisk-cable-length-limitation.
so i ran that harddisk sitting above a cardboard
then that harddisk suffer read-ddmy-dma-error.
then i realised that harddisk-heat comes out from
underneath harddisk as well as from above harddisk.
so much heat comes out from underneath harddisk
even though that harddisk is outside a case....
i was trying to run that old harddisk from dell-dimension-8250
to transfer files from my other computer with broken-linuxmint.
i tried to play crash-bandicoot video-game in my linuxmint then
i can not boot my linuxmint. then i use that
old harddisk from dell-dimension-8250, to save files
from my linuxmint.

year 2008, during working in iowa-state-uni->veterinary-diagnostics-lab, my supervisor randy-berghefer give
flexibility to custom-order dell.com->optiplex-mid-tower-desktop to me. i choose 2 western-digital->raptor-10,000-rpm hard-disk.
1 western-digital->raptor-10,000-rpm-hard-disk fail then dell-warranty renew that failed
western-digital->raptor-10,000-rpm-hard-disk.
now i realise that western-digital->raptor-10,000-rpm-hard-disk must have been hotter than normal-and-usual
7200 rpm hard-disk.
dell.com did not put hard-disk-fan to cool-down that 2 western-digital->raptor-10,000-rpm-hard-disk.
so dell.com has good-warranty. but bad-design ? or maybe dell lack supplier willing to supply hard-disk-fan.
i resign-then-left-2-week-after-randy-berghefer-approve-resignation-request, 19-nov-2010 i stop using that dell-desktop.
[addition 4 sep 2020 9:49 pm edt]

antec.com->antec-300-desktop has a place for hard-disk-fan but antec.com did not put hard-disk-fan.
antec.com-customer must buy hard-disk-fan separately. so maybe antec.com suffer problem finding hard-disk-fan-supplier
as well.

every-time i attach hard-disk-fan to computer-case, hard-disk-fan-screw-hole become bigger then eventually screw
can not attach hard-disk-fan to computer-case.

i think event sequence :
[addition 18 dec 2024 9:35 pm est]
(1)in linuxmint.com->18.2->cinnamon : keyboard stop working , use mouse to click restart-button then keyboard work again .
i forgot to check /var/log/syslog for error-event during that time . this happen 2 time not consecutively .
[/addition 18 dec 2024 9:35 pm est]
(2)linuxmint.com->18.2->cinnamon freeze/become-non-responsive suddenly .
i memorise time-during-non-responsive-event , reboot then check /var/log/syslog and i can not find any event during time-during-non-responsive-event .
event prior time-during-non-responsive-event seems non-error-event and non-relevant .
and that non-responsive-event happen 3 time already , last 2 non-responsive-event happen on around 6:30 pm 2 consecutive day .
but i only start checking /var/log/syslog for that last non-responsive-event .
(3)i insert linuxmint.com->18.2->cinnamon-live-usb then reboot then i select menu 'memtest-86' to test memory then
during memtest-86 to test memory , error-message 'unexpected interrupt halting cpu0' show-up while screen is non-responsive-and-show-flicker-debris
but there is no actual screen-flickering .
[addition 18 dec 2024 4:30 am est] end 4:42 am est
and while that error-message 'unexpected interrupt halting cpu0' show-up , many memory-error-message in red-color also show-up .
so just like https://www.reddit.com/r/Ubuntu/comments/ecgmpi/kernel_panic_along_with_failed_memtest86/ from reddit.com->search ( memtest86 ) .
so i think memory is bad . do i buy 2 gb memory for testing or 4 gb memory for real usage . maybe i buy 2 gb memory for testing only .
if that 2 gb memory can make my computer work then i buy another 2 gb memory to fill empty memory slot because empty memory slot gather dust
and dust is bad for motherboard . i realise i have 2 2 gb memory and all those 2 2 gb memory is bad ? can not make my computer do post/power-on-self-test ?
that is difficult to believe .
this memtest-86 seems run forever never stop like my computer stopping :

then my computer turn-on and monitor show message 'no signal' .
(5)if i turn-on my computer then monitor always show message 'no signal' .
i can hear psu is running , fan is running . so i think psu is working , but i curious is psu providing enough ampere or not , i do not have multi-meter
to check .
i think i want to bring my computer without hard-disk to ubreakifix.com to be inspected , i feel suspicious memory-or-motherboard is bad ,

i can hear psu is running , fan running . so i think psu is working .
so i think motherboard is mortem . i make mistake , i did not know about motherboard-beep-speaker which produce beep indicating error-code .
14 dec 2024 around 11:34 pm my mother order motherboard-beep-speaker for me from amazon.com , i ask my mother to order so my mother can refund
that motherboard-beep-speaker in whole-foods-grocery-shop if that motherboard-beep-speaker does not work . but that motherboard-beep-speaker
estimated arrival date is 26 dec 2024 . i need motherboard-beep-speaker to know psu fail or motherboard fail ?
now i am check price of motherboard , cpu , memory .
i realise pre-owned motherboard is maybe half-mortem , so i want new motherboard , and new generation motherboard need new generation cpu
need new generation memory , so i am shopping new motherboard , new cpu , new memory .
and i am still thinking about bringing my computer to ubreakifix.com because i hesitant about buying thermal-jelly for just 1 usage .
but i think whole usa , this semi-ocean-shore-city usa->virginia-state->fairfax-county->springfield-city is not customer-service-city .
male-hair-cut-price is 35 usd or 40 usd , government-swimming-pool-entry-price 11 usd , everything is expensive in this city near usa-capital-city-dc .

how can you know motherboard-beep-speaker-plug-location in motherboard without reading motherboard-brand-user-manual ?
motherboard-beep-speaker goes where ? then that manager point to many location on my motherboard while telling me what that location do ,
then i repeat my question : motherboard-beep-speaker goes where ? then manager point finger to wrong location on my motherboard then i cancel my service-request .
that manager say i think i am smarter than his technician . i reply i think manager is incompetent and does not know how to manage technician .

15 dec 2024 10:15 pm est :
i worry my psu is culprit in making my computer can not boot
---google ( failing psu monitor no signal ) result 1 :
now i feel suspicious psu is failing :
If your monitor shows "no signal" and you suspect a failing power supply unit (PSU), it likely means the PSU isn't providing enough stable power to your graphics card, causing it to not output a signal to the monitor; this is a common issue where a failing PSU can manifest as a lack of display on your screen.
Why this happens:
Voltage fluctuations:
A failing PSU can produce inconsistent voltage levels, which can disrupt the graphics card's operation and lead to no signal on the monitor.
Insufficient power:
If the PSU is nearing the end of its life, it might not be able to deliver enough power to run your system properly, especially under load, causing display issues.
What to do:
Check basic connections:
Ensure all cables are securely plugged into the monitor, graphics card, and power supply.
Try a different video cable to rule out cable issues.
Test with another monitor:
Connect your computer to a different monitor to see if the problem persists. If the other monitor displays properly, the issue is likely with your original monitor or its cable.
Check for other signs of PSU failure:
Listen for unusual noises from the computer case, especially when powering on.
Notice if your computer frequently restarts or freezes unexpectedly.
Smell any burning odors which could indicate a failing component.
Replace the PSU:
If you suspect your PSU is the culprit, it's recommended to replace it with a new, high-quality power supply unit.

Monitor no signal after start up
Hello.
So just today, I have this problem where my monitors does not display anything after start up. I would turn on the CPU and everything runs fine (fans, power supply, etc) but my monitors stay undetected as if my computer was never turned on.
I did some research and, so far, I've tried:
-removing all or some of my RAM and switching them through diferrent slots.
-removing and reinserting my PCI and my graphics card
-resetting CMOS through the jumper switch and battery
-unplugging everything from the Power Supply and replugging.
-pressing the CPU on/off button for an extended amount of time.
So far nothing has worked and I'm completely stumped. Everything was working fine until my computer randomly crashed darker today and then froze in start up to now not displaying anything. Any help would be highly appreciated and thanks beforehand.
My specs are-
-8 GB ddr2 ram
-quad core Intel
-nvidia gt640
-corsair tx650 power supply

Are you getting post beeps on startup ? If not you may be dealing with a power issue . Just because your fans are running and your motherboard light comes on doesn't mean you have enough power in the power supply to run the machine .Power supplies can die slowly and still appear ok .If you have access to another power supply try changing it out . You may also want to try a different monitor or test your old monitor on another computer. depending on your motherboard you could try resetting the mem button common on Asus boards. Also you mentioned you've disconnected the power and that you've held down the power button for extended periods . Did you do this together? if not try unplugging from power and holding the power button down for roughly 60sec then plugging in and rebooting. Finally as dumb as this is going to sound but it happens to the best of us... is your monitor turned on and plugged in? Just sayin Hope something here helps and good luck

---google ( ami bios voltage level issue ) result 1
AI Overview
Learn more
An "AMI BIOS voltage level issue" refers to a problem where the voltage settings within your computer's BIOS, specifically the AMI (American Megatrends Inc.) version, are not configured correctly, potentially causing instability, crashes, or even system failure due to incorrect power delivery to critical components like the CPU.
Key points about AMI BIOS voltage level issues:
Accessing voltage settings:
To check or adjust voltage levels, you need to access your computer's BIOS by pressing a specific key during startup (usually Del or F2) and navigate to the "Power" or "CPU Configuration" section where you can find options to modify CPU core voltage, memory voltage, etc.
Potential causes:
Incorrect settings: Manually setting voltage levels too high or too low can lead to issues.
Outdated BIOS: An outdated AMI BIOS version might have bugs or compatibility problems with newer hardware, affecting voltage regulation.
Hardware problems: Faulty voltage regulators on the motherboard or a failing power supply can also contribute to voltage level issues.
Symptoms of a voltage level issue:
System instability: Frequent crashes, random reboots, or blue screen errors
Overheating: CPU or other components running excessively hot
Boot failures: Computer unable to start properly
Performance degradation: Noticeable slowdown in processing power
How to troubleshoot:
Check current settings:
Access your BIOS and review the current CPU core voltage settings.
Reset to defaults:
If unsure, load the default BIOS settings to start with a known stable configuration.
Adjust voltage carefully:
If necessary, make small incremental adjustments to the voltage level, ensuring it stays within the recommended range for your CPU.
Update BIOS:
Check for and install the latest BIOS update from your motherboard manufacturer.
Check hardware:
If adjusting BIOS settings doesn't resolve the issue, consider checking the integrity of your power supply and motherboard components.
Important considerations:
Consult manual:
Always refer to your motherboard manual for the correct voltage ranges for your specific CPU and hardware configuration.
Overclocking caution:
Modifying voltage levels can be particularly important when overclocking your CPU, as setting it too high could damage your hardware.
