Random BSOD while playing video games

Hello, usasma.

I've done as you asked. I ran Small FFT's and whilst I had no errors or bluescreens the temperatures reached 98°. I wasn't sure how long to run it for and the temps seemed very high so I stopped after about 5 minutes.
When I ran the Large FFT's I got a bluescreen almost instantly.


I will try the Intel processor diagnostic tool later on today.

Edit: Unable to use IPDT. Getting the message "A newer version of Microsoft Visual C++ 2010 Redistributable has been detected on the machine." when trying to install. Will try Intel Burn Test instead.

As usasma already mentioned, do not continue with the tests until you get the CPU cooling under control. Those temps are dangerously high and are indicative of an improperly mounted cooler.
Who installed the CPU cooler?
You mentioned this PC is still under warranty. If that is the case, and the builder installed the cooler, you may want to verify that you re-seating it won't void your warranty.

Ah, crap... Unfortunately I didn't see your post in time and have already used Intel Burn Test.
Temperatures again peaked at 98° but all tests from standard to maximum came back with no errors and no bluescreens though I have no idea what to make of the results in the bottom window.
I should probably note that it doesn't get this hot with normal use. If I remember correctly the hottest it's ever been when playing a game was 70° (according to Realtemp).

I've looked at the CPU cooler before but didn't notice anything unusual (then again I'm no expert). If it's not been mounted properly would I be able to tell just by looking at it?
The machine was built by Wired2Fire. I'll get in touch with them and find out if re-seating the cooler will void the warranty.

By the way, I have no idea how to re-seat the cooler and don't feel particularly comfortable taking it out. Is it easy to re-seat? I'd rather not cause any damage to the machine by fumbling around inside it.

Okay, update. I recieved an email from Wired2Fire who told me to remove the overclocking. You told me it wasn't overclocked but I followed their instructions anyway (didn't feel comfortable doing this but had nothing to lose) and went into the bios and reset everything to default.

I then ran Prime95 blend test and temps did not exceed 60°. I couldn't even hear the cooler! Better still, no bluescreen. I've only run it for about eight minutes. I'll let it run overnight though to be sure.
Intel burn test also did not go higher than 65°. Is this a good temperature? It's a hell of a lot better than 98°.

So I'm hoping this has solved the problem. Looks like a bad overclock I guess? I'll soon find out. I hope reseting the bios hasn't made this gaming computer rubbish.

I'll let you know how I get on with Prime95 tonight.

Prime went overnight with no bluescreens and no errors.
I think the problem may have been solved.

Thank you for all your help.
