comp keeps crashing

Specs: Windows XP, 2.4/2
i have a computer with ok specs Q6600 CPU, 2 gigs ram, 7600 gt card. In the past, ive played relatively demanding games like assasins creed, quake etc on the highest settings. Recently, my computer makes a high pitch hissing noise every time i do anything even remotely demanding. i cant even play older games like WoW for a few seconds without the computer crashing and giving the blue screen error message. sometimes, even opening too many windows at once causes the computer to freeze and crash. I have added no hardware/software in the last few months. This crashing always coincides with the high pitched hissing noise coming from the computer... i know there isnt much to go on but can someone please help!

Get a new cooling fan for your CPU and while you are at it get a new Mainboard because you have probably damaged the CPU by letting it over heat.

The CPU *may* be overheating, but there are no temps listed so that would be strictly a guess. It could also be a problem with the video card or the power supply fans or the case could simply be full of dust. Not enough info was provided.

If you haven't cleaned the inside of the case lately, open it up & blow out the dust with compressed air, especially the heatsinks & cooling fans. Do NOT use a vacuum. And while you have the case open, get the power supply specs off the label...make/model, wattage & amperage specs. Temporarily leave the side panel off the case.

Bootup & immediately enter the BIOS...go to the PC Health menu & monitor the CPU temp. Report back what it is. If the high pitched noise is still there, see if you can pinpoint where it's coming from.

A couple more do nots

1. Do not run out and buy a new cooling fan.
2. Sure as hell do not buy a new mainboard.

Do give us the power supply information jam asked for.
Do try to exactly locate the noise.

ive opened up the case.. cleaned everything out.. and tried to elicit the cause of the noise.. no luck so far altho i think it may be the CPU
also, CPU usage jumps to 60%.. and the comp temporarily freezes whenever i open a new window or watch a video...
playing a game, causes the CPU usage to spike and then the computer to crash..
any further suggestions please?
