I just built this comp in december 08. Ever since I've been having problems with graphic drivers. I am so going back to Nvidia after this...anywho I have a ATI Radeon HD 4850.
I know for sure it's not the monitor. I just did 6 hours of work trying to figure it out. Cleaned/dusted it. Cleaned out old drivers. Tried 3 different drivers multiple times each. The newest one from their website, the one that came with it, and the omega one.
I am getting several different types of errors. The "ati2dvag display driver has stopped...", graphical anomalies (like 3 red bars and distortive effects) even in safe mode sometimes, and finally it will lose connection...like literally the screen goes blank, the monitor says its no longer getting the signal but I can still hear say music playing indicating its working fine otherwise.
Like right now everything is working perfectly. But if I go into a game I get one or more errors and have to restart. And the really annoying thing is that half the time I have to re restart because it all loads up normally but then just as its about to load the desktop it loses signal.
This is really some strange random stuff. I can't figure it out. Help!
PS This is the omega driver I was talking about.

Also, the reason I'm thinking driver and not video card is that I can go into safe mode and uninstall the driver, and then reboot and it works fine (besides the fact it doesn't have a driver anyway).
