About two days ago on my computer while I was trying to watch a trailer at gametrailers and moved the screen suddenly the computer went all slow on loading really not that unusual, but then suddenly the screen flashed a couple of times and when i tried to close the window an error sign popped up saying something aboiling to shutdown or something like that and then the internet screen popped up again and I noticed that all the colors were scrambled and they stil are the boards on Eyes on FF are grayish and the banner is all spotty. I thought restarting the computer would fix it and after trying about 6 times to shut it down with the keyboard and mouse it finally shut down, but when it restarted everything's still the same the colors are scrambled and blurrish and every image and toolbar is large what's going on what's up with my compute?
