Crashing and rebooting

I’ll TRY to be short.
First ran DVDDecryptor,showed all info ok. Started the process it gets to about 50% and screen goes blank and a beeping sound. Have to reboot comp.
Than ran anydvd no problems. Open Clone DVD, all info seemed ok. Right after i started to copy files the comp. rebooted by itself and this is a disk that I COPIED BEFORE with the same programs with no problems.
I tried DVD Shrink too,allinfo looked ok,than during the create file process the comp. started beeping and the screen went blank and locked up.
