Hello everyone.

I've recently come across a problem that is annoying the crap out of me.

The BSOD happens when my friend plays WoW. The time seems to be random.

Below is the entire BSOD cut 'n' pasted:

Finished dump check

I know it has something to do with drivers. I'm seriously stumped though. I've updated a few drivers but it still crashes at random.

The computer itself, is run by an extremely novice user that likes to look at pr0n and NEVER update his drivers. I found device drivers on his computer dating back to 2001 and 2002.

I don't really know what the unloaded modules section means but could that be pointing to the source of the problem being the sound card?

Are you using onboard audio drivers? That BSOD indicates the problem is kmixer.sys, which is the Microsoft Kernel Audio Mixer. So update the sound card drivers or if it is onboard, update the chipset drivers from the chipset manufacturer's page.

Thanks for the quick reply.

It's a PCI SB live card so I update those drivers. He has no idea what the card is and the drivers it's currently using is from 2002. and since I'm doing most of this remotely, I basically have to go over there and crack the case to see what it is.

Thanks again!
