Video Card Problem

[Spriggan]

Well my problem is like no other listed... I can boot up and load fine, but after around five minutes of playing my video card turns off. I have only experienced this problem in BF2 on the night maps before they fixed the shader. I can still hear the game and stuff but there is no video. I was wondering if anyone had experienced this.
My videocard is the Ati Radeon x1800XL, I play DoD:S, BF2, CS:S, and COD2 all on full settings so I was wondering if there was a support issue. I am also in the process of reloading the game, I have had it since the day preloading started so there could be and issue there...
Thankyou

::Bump:: I reinstalled the game but with no avail.

if you had the same thing in bf2 and they got out a fix then its just the waiting game you will be playing

are all your drivers up to date ?

[Spriggan]

Yeah drivers are up to date, Ive tried the normal Catalyst and the Omegas but its still no go bot a big blue screen telling me that I had bad IRQL whatever the **** that is.... I hope that I'm not the only one and that this gets fixed.....
