In the last couple of weeks i have noticed some fairly serious pixelation/ graphics shredding whenever i watch videos online or on my hard drive. also lately i have noticed a similar issue on my web browser..... please any help would be immmmensely appreciated.

AMD Phenom II X2 555 (unlocked 3rd and 4th cores)
ASUS M4A785-M .mobo
Ultra 550 Watt LSP .PSU
Western Digital Caviar Black SATA 500Gb. Hdd

P.S. Windows update also wont work, idk if thats related or no, but it is odd.

You're using on board video right?

If you're experiencing pixelation, then something is choking in your system. Try disabling those to cores you unlocked.

2GB of ram might not be enough. Widows 7 uses up a lot of ram. You should really have 4GB.

Either bad cores, bad GPU, bad PSU or bad RAM.

Hard to say with that system.

Start as noted by disabling those core and removing any overclock. Then run prime 95 overnight for 12 hrs or so, see if errors pop up.

Current PSU is junk, could simply not be providing clean power to components. Swap in a good PSU to test. Normally I'd say you could also swap a component into a working pC, but that PSU might just fry your working PC.

RAM can be tested with memtest. Run it overnight for at least 8 passes.

GPU could also be issue. If you have a discrete, then swap test. If you're using integrated, disable and swap in a new GPU to test.
