Greetings TPU, A dear friend of mine have had a longrunning problem now. I've tried a lot of different solutions, but nothing seems to fix the problem. We've tried formatting his computer with a different OS and much more; he also have the newest drivers for his graphics card and everything else. His hardware is as follows: CPU: Intel Core 2 Quad Q6600 MOBO: DFI Lanparty LT X48-T2R RAM: 2x2GB DDR2 (Can't remember the brand) GPU: 2xATi HD3870 in CrossFire (512mb each) I've also dugged out his crash dump file, so if anyone would like to have a look at it, here goes: I know it's a display problem, and I'm pretty sure it probably one of his cards that have some sort of problem. Any suggestions before I tell him to get a new card? Thanks, Valen P.S. There is no Overclocking of any kind on the system. P.P.S. This almost only happens when playing World of Warcraft. I've recently updated his drivers to the newest available, which seemed to make the problem worse.
