Ok. I finally recieved my copy of Elder Scrolls IV: Oblivion. I've had it for about a week now. My system is:
Radeon X850XT PE PCI-E
P4 HT 3.0
Windows Xp Media Centre Edition 2005
The day I bought the game I updated my video card drivers to Catalyst version 6.3. I have been playing the game up until today. I logged into my computer, and my desktop freezes. All my icons are there, but nothing works, and when I put my mouse over the start menu, that waiting cursor appears, and all i can do is use Ctr+Del or restart my computer. I think it is the video card drivers because in the system tray, the ati icon always appears, and now doesn't when I start up. Also, I had been getting overheating issues with Elder Scrolls Oblivion, and when exiting the game, always crashed. All this is giving me zero access to my computer. I hope someone can fix this.
