Ok, I'm a not very informed on what info you may need but I will give all info that MAY help...

The problem started yesterday when I noticed a problem with what I believed to be my video card. On black parts of the screen I noticed colored pixels that would move as I scrolled.
Then today I was playing one of my MMO's and it froze up twice about 10sec into playing both times with repeating sound as it was froze and both times I had to power cycle to get out.

Then I decided to clean up my system a little and uninstall a few programs and twice while deleting programs my computer froze up completely.

Not sure what I should do...let me know if more info will help,

Thank you

The coloured pixels are known as artifacts and generally mean the video card is on the way out and should be replaced. Even more the case if artifacts appear on screen during instances where there is no driver involvement at all (such as in the BIOS and on the POST screen). Alternatively out-of-date drivers (if the artifacts appear in Windows) can cause this.

Hi, do you use vga card? or integrated video?

if you use vga card, you might want to clean its heatsink/fan and re-apply thermalpaste on its chip (below the heatsink/fan)

--edit--
please be careful if you decide to re-apply thermalpaste as most thermalpaste are conductive.. :) the best thermalpaste to use is the non-conducting such as Artic Cooling MX-2 or CoolerMaster Nano Fusion.

If the OP has a separate graphics card and said card is under warranty, taking it to pieces as described above will invalidate the warranty.
The issues described by the OP are most likely driver related.
