Thanks for both of your input, here is what i have done and the results..
I have run the hard drive diagnostics, but have had some problems. When i unzipped the file i tried to run it and after pressing Y for accepting the terms and agreements, the test quits. I tried it over and over again. Is it a test that preforms in the background and then shows the results up later, or by nothing happening does it mean that there are no problems? I had put the file on a flash drive and booted the system up from it, it did nothing. Am i doing something wrong?
Attached is the everest report you suggested.
Also I have 3 sticks of 1GB ram in my computer, i just recently removed the 4th stick because it was made by a different manufacturer. I ran memtest86 when i had all 4 sticks in, do i need to run again?
