BSOD "IRQL not less than or equal" on my new yoyotech PC

[Llansam]

Hi,

I bought a lovely new PC from Yoyotech a few months ago (see specs below) and everything was great until a few weeks ago. I keep keep suffering from (seemingly) random blue screen of death crashes with the error "IRQL not less than or equal" displaying and the computer restarting. These crashes sometimes happen every 5 minutes, but sometimes hours will go by without a crash. I'm fairly certain it's not heat related. Crashes seem to happen more when I'm streaming videos on YouTube (I could be imagining this) but I've yet to have a crash while gaming (and I'm playing pretty high-end games like Bioshock and Crysis at full whack).

An extensive Google search on this subject helpfully suggested that it could be ANYTHING. I've re-seated all of the hardware and have switched my 4x1GB of RAM about in every conceivable combination (including running with just 3 sticks, and taking a different stick out each time). Windows suggests that perhaps I should upgrade my BIOS. This will be my next step though I'm slightly daunted by the prospect as I've never done it before and it looks complicated. I was also wondering if this would void my warranty with Yoyotech?

Any advice would be most appreciated!

Thanks in advance,

Sam

I take it you have updated your drivers on your system.

[Llansam]

Yep. I've updated all my drivers. Still getting the restarts.

Update:

I ran Memtest86 overnight and memory checked out OK. Turned on computer this morning, browsing the internet for a minute and bang! BSOD. Exactly the same message. Argh, this is really frustrating!

What next? Should I update the BIOS?

Would appreciate a response from Yoyotech.

Cheers,

Sam

that's the error i get when trying to OC my memory.. if i tighten the timings too far it'll begin to boot into Vista then it'll BSOD with that exact error code.
possibly check your memory?
