Ok, sorry I didn't get back sooner... Anyways, I think it has something to do with bios/jumper settings. Yes, I did reinstall (the os). I tried reinstalling the driver a couple of times, but not directx. The reason i think it is a jumper setting and/or bios setting is because when I tried to install xp 64 beta, it came up with a blue screen telling me to either upgrade my bios or get a new video card. Does anyone know what voltage the 8500dv needs? I found where I can up it to 1.6v or 1.7v. Perhaps it needs more voltage? I've heard that older cards do. Any more ideas?
