I just started getting this error too?! I play FarCry a lot... sometimes it will blank blue screen (with weird sound clips) after 2 min... and sometimes it will happen after 20-30 minutes. Occassionally, I can Ctrl + Alt + Del out and get back to Explorer, and sometimes the PC just freezes up (forcing me to manually reboot). The FarCry error log (which usually works very well) doesn't log the errors, making me believe it isn't the game (software) at fault. I also have an X850XTPE card. I currently have my PC running at ALL default speeds, NO overclocking whatsoever. I have ran Prime95 (to test my CPU) for 10+ hours with no problems. I have ran MemTest86+ (to test my RAM) for 10+ hours with no errors. I did a clean install of Windows on a new Hard Drive (with a new SATA cable). The problem still exists... so possibly it is the video card Very Upsetting... I guess I will take the cooler off, clean it, reapply AS5, and reseat the cooler tonight. Hopefully that will fix the problem...
Silencer, please keep this post updated with any new info... I will do the same
-Thanks
