I'm not sure if this is the right section to post this (I'm new here) but here I go. Basically, anytime I try to play World of Warcraft, the whole computer freezes and I have to manually restart it. I think the computer would restart itself but I unchecked "Automatically restart" under the Startup and Recovery tab in Windows. I have an ATI Radeon 9800 pro and also unchecked "enable VPU recovery" from some advice i got somewhere else. The idea behind doing both of those is that it shouldnt have to do either of those in the first place if everything was working right. I'm kind of a noob at fixing problems so bare with me. I have a suspicion that my power supply is to blame but I'm really just guessing here. I have a 450W power supply that came with the case I bought so it might not be the best. I put the rest of my system specs in a .txt file (using Everest Home Edition) so you guys can see. Any help?
