Hello there, and first of all, thank you for taking the time to read this!
My computer issue is that everytime I start playing a full-screen game, my computer gets this checkerboard-like green and purple vertical pattern, like 4 or 5 sections of it. Sometimes, it just makes so many lines go crazy and it looks like the lines are dancing or something, and makes the game obviously unplayable. The games, if it even matters, it seems to effect every game I try fullscreened, are: Elder Scrolls Oblivion, Far Cry, World of Warcraft, and Star Wars Empires at War. Those are the only ones I have tried since having this problem, but like I said it probally will happen on any given full-screen game.
-But- when I run the same game in windowed mode (even if I check an option that makes the borders go away and everything else, so it appears to be full screen) it works just perfectly.
If I think of anything else to add to this I will, and I'll keep checking back frequently. Also, I am not the sharpest tool in the toolbox when it ocmes to computers, but my PC is a few years old, and the video card is only 1 year old. The video card is a Radeon x800 (I could be totally wrong, but I think it's something like that...) and my computer is a eMachienes. I have never had this problem before untill very recently, so it puzzles me... :-?
If I can get full-screen games working again I will love you forever! (Because I just bought a game that doesnt support a windowed mode, and I'd hate to see 50 bucks wasted)
