I had my computer unplugged for about three weeks, and i recently booted up. I found that my screen is pixelating in different ways. I don't think it is a problem with my LCD screen because the problem goes away temporarily when I click elsewhere on the screen or switch programs.

The pixels are small blue blocks that sometimes form checkered patterns. Sometimes the pixels are random black dots & lines that appear in the middle of the screen as i type. Sometimes it simply looks like interference, and this typically happens on the start button or the taskbar. All these symptoms happen randomly and change often.

That being said, i never encountered this problem before, and im not sure if it is hardware or software related. I checked device manager, and there doesn't seem to be a problem with any components there. Anyway, here are some of my specs:

Intel Quad Core Q9550
4GB memory
AMD Radeon 7750
Intel SSD 520 series 180GB


Btw, my computer has been acting very weirdly lately. Since ive done an OS reinstall a couple of months back, ive been getting loads of BSODs. Im not sure if those have anything to do with this new issue. I included a link to a picture i took that shows what it looks like [hopefully it works!]. Any help would be greatly appreciated! Thanks!

Solution
Restrict the power draw of your video card using the ATI drivers, and consider underclocking it by 15%, then gradually bump it back up to normal clock speed (keeping max power draw limited using CCC) or until you get ANY issues with it,... it may end up 10% underclocked or 3% underclocked for example.

This is much better than killing your system, video card and/or motherboard.
