i have another PC.
i bought a 22-inch Chimei LCD, for that PC, back in February. i have seldom used that PC since then.
i have encountered a problem with it, which has never happened before ---- the PC automatically shuts down. it happened again today (it's the 2nd or 3rd time it happened).
pressing the power button does not/cannot turn the PC on (PC does not boot). but i noticed the keyboard & mouse are still lit on (remember the PC is off). i can turn the monitor on too, but of course, there is no image/monitor is black.
the last time it happened... what i did was let the PC rest for a few minutes, reconnect the power cords to the AVR (auto. voltage regulator), then it turns on & works ok, like nothing happened.
if it helps, that PC has been having a ringing sound during boot time, since mid2009-Jan2010.
i do not have an idea what the cause is.
but my guess is that the problem has something to do with the new monitor.
the old monitor was a 15" samsung LCD.
..another guess is the power supply. since i upgraded to a bigger monitor, this may be related to it. (a few minutes ago, right after the PC auto shut down, i touched the Power supply casing it was relatively hot)
my power supply is 300W, it came with the PC when i bought/assembled it around 6yrs ago..
Hopefully someone can help
Thanks all!

Greetings all!
i've written & posted the above post last July 6, 2010 in another forum.
within 1week of that posting, i replaced the 300W PSU with a new 500W PSU.
below was my July11 post
July12 - 16 2010
i still hear ringing sound during almost every boot-up.
PC automatically shuts down several times; a few times, it shuts down after a few hours of usage, much fewer times it shuts down in less than 1hour of being open. i was doing spyware check/antivirus check, leaving the PC on (with monitor turned off to save power), & when i came back the PC is turned off (but keyboard & mouse are still lit on).
trying to fix the problem myself, i used PC2's video card (Nivdia geforce MX 440). PC1's video card is Inno3D Geforce FX 5500. using PC2's video card, i never heard a ringing sound. seeingthis, i suspected the FX 5500 is the culprit. in the other forum, a poster mentioned changing the Video card solved the "auto shutdown" problem. so i thought this was the cause.
July 17, 2010
i was able to successfully install a wired router connecting this PC (the PC im using right now; i installed the router in this PC; from now on we'll call this PC2) & the above mentioned July6 PC (which we'll now call PC1). that day i was able to use PC1 surfing the internet, using PC1's FX 5500 vid.card.
July18
when i tried to use PC1, (FX 5500 inside), during boot up. i got a BSOD.
the stop error message was
0X000000ED UNMOUNTABLE_BOOT_Volume
specific info found on microsoft support page & kadaitcha website
(it's my first post, so im not allowed to post links)
im surprised getting this error message because, i didnt install any new hardware or software. i had PC1's original video card installed, which is the Inno3D Geforce FX 5500.
i never touched/removed the RAM, or any connectors/device/component etc..... i only installed/removed the FX 5500 vid.card (to test if it is the one causing ringing sound/auto shutdown)
i can remember doing a minor change on the BIOS settings.
on "Primary Graphics Adapter", i changed it from "PCI" to "AGP"
(i went inside the BIOS settings primarily to check if video card "Fastwrite" settings is Disabled, well it was Disabled; 'Fastwrite' was mentioned to be 1 of the FX5500 problems in a few forums)
the stop error message seem 'inconsistent' with my assumed video card-led auto shutdowns.... unless the BSOD is a harbinger of much worse PC problem.
AMD sempron
1.5GB RAM
i will give more details about my PC specs tomorrow. (i'll try to boot PC1 again to get details)
{i checked several times; there are no blown/burnt capacitors/MOSFETs}
any insights/replies will be appreciated. Thanks & God Bless!!!!!!

below was my July11 post
i bought a new one a few hours earlier.
i just tried it.
during the first attempt i still heard a ringing sound, but it was considerably shorter in duration & quieter in volume. (video card may be another culprit)
during the second attempt, it went smoothly.
Thank God.
will monitor it for about a week.
