I own a Dell XPS 420 with an Invidia G-force 8800 graphics card. I run Windows Vista and I've owned the computer for 14 months. For the past week or so, whenever I try to use the computer, i.e. surfing the web or playing City of Heroes, my computer screen will freeze and pixelate. I'm not 100% sure this is a hardware problem, so I would like to find out if it's just a part that needs to be replaced or if I need to reinstall my software.

Thank you!

Should be either a memory or video card issue.

You can test the system memnory with Memtest86,

http://www.memtest86.com/memtest86-3.5.iso.zip

Unzip the ISO file
Use a program like Nero with the "Burn Image to disk" feature to make a disk from the isp.

If you don't have a burning program that will do ISO files download ISOrecorder

http://isorecorder.alexfeinman.com/downloa...corderV2RC1.msi

You can install it then right click on the ISO file & click on Copy image to CD to make the disk.

Boot the disk & let the test run all the way through [I think the are 8 tests] at least once.
If you get ANY errors you have bad system memory.
If you get no errors more then likely the problem is the video card.
