I have a problem with my computer and it is driving me crazy.
I just started using this computer 2 days ago and installed windows updates and things I missed out over the summer. I also updated Left 4 dead and dawn of war 2 on Steam and downloaded the Arkham Asylum demo.
Now the problem is this: whenever I go into Dawn of War 2 or L4D, the image gets all out of whack. What I mean to say is that the image gets all scrunched up to the right side of the screen and the rest is just black.
This doesn't happen in the AA demo. I also tried other games outside of Steam (Fallout 3, XMEN Origins Wolverine) and this doesn't happen in those games.
I verified the data in Steam for both games and ran them again and the problem persists. The very first time this happened, I had doubleclicked on the Catalyst icon in my taskbar and the screen went black for a second or two and my desktop had been scrunched up to the right side of the screen with the rest being black. Also, there is a white line running from the top to the bottom on one side of the screen that disappears whenever the image is fine.
I'm running Windows 7 RC x64 and have an ATI 4870 512MB. Please help, this is driving me crazy.
EDIT: I played DoW2 last night for a couple hours last night and it worked fine. Nothing in my computer is overclocked. I have a Benq v2400HD and it's connected through VGA.
