3870X2 problem

[J86]

i have a 3870x2 on an asus p5n32-e sli plus which has the latest drivers.

i can sit on xp fine, but when i play cod4 for 5 mins, the screen turns off and i have to reboot.

i have both the 6 pin plugs into the card, and the fan running perm. on 40%

running cat 8.4

any ideas? case has excellent ventilation

thank you

Thanks for the replies

Confirmed it's my motherboard causing it.

Thank you again
