|So it could be the power supply that is causing the PC to restart when only 1 or 2 specific software applications are started ?|
Imageburn and Starburn cause the restarts and sometimes closing the drive with a DVD in it will too.
Alcohol 120% doesnt read the drive (for some reason) but at least doesn't restart the PC. However Windows and CopyToDVD (and some others) DO read the drive and don't cause a restart and work just fine.
Why would a power supply only be affected by a certain 2 progs?
I could see the DVD burner because of the power draw when closing it with a DVD.
Thank you for your help too.
