Random bluescreen crashes :/

I played SL for a few days, a few months back, and I never recall having these problems. Since my friend asked me to return yesterday, I've been getting random bluescreen crashes, which started off being every couple of minutes, but have now slowed to every 30-60 minutes. None of the other games on my system are doing this and I've never seen this particular bluescreen before.

The only thing is that I'm running some slightly older graphics card drivers, as the latest ones seem to spaz out all the time. But this doesn't surprise me, from nVidia. Besides, the error doesn't look like it came from the graphics drivers. I'm running WinXP SP2, and the relevant details from the BSOD are:

DRIVER_IRQL_NOT_LESS_OR_EQUAL
STOP: 0x000000D1 (0x0000000C,0x00000002,0x00000000,0xF6C0D6FA)
tcpip.sys - Address F6C0D6FA base at F6BFF000, DateStamp 411107ecf

I've updated all the drivers on my system, and still keep getting it. Any ideas what it could be? It's getting really annoying.

Uhrm.... Random thought, but check the drivers to your network card.

That error message comes up (usually) in the case of a bad driver, in this case, tcpip.sys. So yes, check your networking drivers.

Sadly, that was the first thing I checked. I got that error with the drivers that came on the XP disc, and exactly the same error when I updated to drivers off the Realtek site.

Eh, maybe the card's just screwed. They're pretty cheap anyway.
