Help!!! this is getting on my nerves lol. i dunno what else to try. ive tried new vid drivers and new mobo drivers... what could it be?

Check your caps, and to be sure it's NOT a heat prob run with your side cover off.
HTH

caps? have been running with side cover off and a fan blowing into it.

Try running some things like memtest86 and prime95 to see if you can pass those.

recently?

has this only started to happen to you recently if so then go to the steam forum as this may be something to do with the latest update which added in hdr option but screwed uo loads of peoples games i myself have been lucky enough not to be affected but you may have

no. not that recently its been happening for quite some time now.

other games

do you have any other games that would push your system this hard to test it with?

well it sometimes does it with warcraft 3 and counter strike source. although counter strike is practically the same as dod cuz its the same engine.

ok

have u ever had freezing during normal usage?

CAPAcitors =caps.

Likely an unstable processor OC. If you're OC'ing your processor, increase the Vcore. If the problem still occurs, I dunno what to tell you, except that you have an OC wall or the processor degraded.

Even if you're not OC'ing, the Vcore may be set improperly. You should download CPU-Z and see what CPU-Z is reporting for the Vcore. You may have a voltage droop problem, because of an insufficient power supply or bad caps.
