Did you try a simple restore to an earlier time ? If not give that a shot, it may be that something changed in the system and the restore might bring it back to the original state. It is possible it could be video related but since you have normal windows functionality I would first try the restore feature.
I am running an eMachines VISTA OS. I have not been able to open, today, games I'd been playing from a site I frequent. Last night, I had no problems. This morning when I clicked to activate a game, I got a flash of a partial black screen and then it disappeared. I went to the site and searched their 'help' option for a reason why this is happening. They suggested that I need to update my video card drivers. I went to my system's site, and they sought to 'help' me, but were not successful. Later I tried to open a game I'd been playing daily for several months, and got this FATAL ERROR window: "Failed to Initialize DIRECTDRAW: RESULT_SURFACE_FAIL"
Please advise what this refers to.
