I have the same issue. Only occurs when I play BF2142.
I did memtest86 and also had windows check itself (chkdsk).
Everything was normal. It's be doing it episodically over the last month. Last night mid game my card locked up. Rebooted and after 1/2 hour I got the blue screen. Didnt get the stop line.
Card temps are normal at idle and load and 3DMark06 doesnt phase it when I run that. I've used everest to run system stability tests and I cant see anything that is chewing up memory.
Any thoughts? Do I need to repair or re-install my OS?
I installed my ATI dirver (new ones) and then got this message:
stop: 0x000000f4 (0x00000003, 0x87AD6748, 0x87AD68BC, 0x80501140)
So, I uninstalled the driveers and re-installed from a fresh copy.
I went to microsoft support and no info on the last 3 and a google search produced nothing. Since latest reboot, everything seems ok.
