PC restarts when playing games

I was playing Transformers earlier, when my PC randomly just restarted itself...
here's the error code that came up after I rebooted:
Error code 100000d1, parameter1 90dc4f80, parameter2 00000002, parameter3 00000000, parameter4 f80e1a2fhere's the system specs if you need them:
Windows XP Home SP2
2.26GHZ Intel Pentium 4 processor
512MB ram
ATI Raedon 9700 Pro 128MB video card
Creative SB Live! Wave sound cardWhat is going wrong here?

A bugcheck of D1 means the following.0x000000D1: DRIVER_IRQL_NOT_LESS_OR_EQUALThe system attempted to access pageable memory using a kernel process IRQL that was too high. The most typical cause is a bad device driver (one that uses improper addresses). It can also be caused by faulty or mismatched RAM, or a damaged pagefile.

best thing i could find!! just go there and see if it helps!don't know though because i use linux for mainly everything except emulation and dvd movie burning.....never gotten that except when i used xp for internet and the works.

I've tried some more games besides transformers, and it's doing it on all of them...
I tried GTA San Andreas, Super Smash Bros. on PJ64, and sometimes if I play a youtube video in fullscreen...I have directX 9.0c already, should I try re-downloading it?

These problems have always been resolved (in my experience) by upgrading the power supply and/or ram. Not sure if that'll help you, running XP with 512 doesn't seem bad at all so I'm kind of ruling that out.

Do you use Skype?

That particular problem is generally software.Update all your drivers.

The ram is new, but I'll try re-seating itno I don't use skypeas far as I can tell, all of the drivers are up to date...
except for one called Multi Media Audio Controller

thats soundcard. Is your sound built in to the motherboard or is it a separate card?

ok well, we can all just forget about it now... the mo-bo just somehow got fried, and I'm not messing with this thing anymore...but yes it was a seperate card: Soundblaster Live 5.1

didnt read the comments but i use to have the same problem try opening up ur computer cleaning it (getting out all the dust i used a vacume).
im guessing the computer is just overheating coz of the dust but what do i know its worth a shot anyway

Replying to #10

overheating does not cause a DRIVER_IRQL_NOT_LESS_OR_EQUAL bsod.

It was all because the motherboard was beginning to go out, which it did... so now the PC's dead and has been stripped of eveything but the motherboard
