Monitor black out, CPU stops processing but no restart.

Specs: Windows XP, Pentium D 2GB ram
Hi guys and whatever help you could give me on this bizzare issue would be more than welcome.

Sometimes my monitor will just black out,the cpu fans keep running though.But however its not a monitor or a driver issue at all since not only have i changed graphic cards and updated drivers but when an mp3 is playing in the background and this happens,the mp3 stops playing too.So i assume essentially the computer crashes but there's no restart and the fans keep on running.The only way to get back to normal is to unplug the system and then start it again.

Its not a power supply issue either.The psu can easily support the whole thing.No heating problems either.All temperatures well within limits.No problematic cables too.I have read in a forum that I might have some problem with my motherboard,specifically some burnt IC's.Could that be?

The computer is a 5 year old Pentium D with a Gigabyte motherboard.

It's always helpful to backup your statements with "proof". For instance, what is the make/model/wattage of your PSU & what are the CPU temps?

"i changed graphic cards and updated drivers"
"5 year old Pentium D with a Gigabyte motherboard"

Again, lacking specifics. The early Pentium D was based on the Prescott core & had cooling issues. If it's getting above 60C, it could be a problem. And you didn't post the make/model of the video card(s).

I am sorry I didnt give you 'proofs'...The CPU temps hover around 39 -45 degree celsius.The PSU itself is a generic cheap one with a wattage of 550.The video card used was a ATI radeon 5450 which uses very little power and is powered by the pci slot itself.

I ruled out the power issue since the wholesetup worked on a 400 W PSU earlier just fine.Plus the 'symptoms' dont point out to a faulty PSU.Am i wrong?

Could be a bad power supply, so don't rule that out. Take a look at the capacitors on your motherboard, they are the little cylinder looking components on the board. Are any of them bulging or busted. Look closely at the tops of them, they should be perfectly flat, not domed at all.

Other then that, have you tested your ram? Try memtest86

this really could be a bad power supply and\or cpu issue
39-45 at idle or when u do stressful stuff?
if this happens only when u do stressful stuff then a power supply and cpu would likely be the issue.
as gretti said make sure to check ur motherboard caps as well
