[QUOTE="chscag, post: 1381278, member: 46727"] It does look like a graphics problem. If possible, run this test: When the distortion shows up again, take a screen shot of your desktop. Observe the screenshot. If the distortion shows up on the screen shot, it's likely a hardware problem with the graphics. If the screen shot is clear, then the distortion is likely being caused by the LCD itself. You can run the same test by hooking up an external monitor. [/QUOTE]
