Looks like a PSU problem for me. Do you have an extra PSU to test the system?

You need to identify what causes it. Open <b>System Properties</b> by pressing <b><font color=blue>Windows Logo</b></font color=blue> key and <b>Pause/Break</b> key. Click on <b>Advanced</b> tab and go to setting of <b>Startup and Recovery</b>. Uncheck <b>Automatically restart</b>, then shutdown your comp. It should display a <b>STOP</b> blue screen showing which device or application is reponsible.
I used to have this problem before. Turned out it was my Adaptec CD Creator 4.xx that caused it. Uninstalling it fixed this problem on mine.

Good or Bad have no meaning at all, depends on what your point of view is.
