1. First off, what are you trying to do with diagnostic programs? 
2. What programs are you using to run diagnostics? 
3. Are you having issue with computer or motherboard? if so, whats the issue?

My pc beeps after hitting the desktop and I searched the beep code but I didn't get anywhere so I figured I can run some tests.

I used check it professional and a test that's located on a recent copy of UBCD.

I did a fresh install of Windows Vista  with a clean install disk and I noticed when I'd open my documents folder how the Window would show the frame but where you should see documents I just seen my desktop background.
