Ever since I've upgraded to Windows 7..I've been having some issues with it. Usually when I access a file, loading up a game..playing a video, opening a program, etc..my screen will sometimes turn a bunch of different colors and I have to restart. At first I thought it may have been my monitor but then I kept music playing and when this happened...the music was playing but all crackled so an obvious hardware issue. It doesn't happen all the time but I've at least dealt with it 2-3 times a day. I'm on an Asus computer..Intel Core 2 Quad CPU Q8300 @ 2.50 GHz, 8 GB of ram, and using Windows 7 64 bit. Graphics card is Nvidia Geforce GT 220. Also my only previous OS was Windows Vista and I NEVER had this problem. Computer is only a couple of months old. If you need any more info, let me know. Thanks in advance.
