Ive got a 2007 Compaq Presario running MCE xp that I played WoW on until I got my 80 (No issues what so ever) recently WoW has been freezing at the login screen. Ive also noticed that Media Center locks-up as well. Both requiring a hard restart. When they freeze, the hard drive light on the front of the computer stays solid. I bought a new hard drive and installed a fresh copy of XP, only to have the same problem. Whats going on?
