Monitor the temps, ibet its overheating and trying to shutdown.

Make sure all the fans are clear of dust and are spinning correctly.
Monitor the temps in the BIOS? Reason I ask because I noticed his CPU usage maintained 100% in the task manager in safe mode. I am currently cleaning out all the dust from the computer system to see if this helps any. Because it his system does sound rather loud with the fans going that is. But again, even after a clean fresh install it is still doing the same issue. Do you think at this point it is a hardware issue or software? I talked to another guy he suggested to swap the memory around in the system but I am a little skeptical about doing that. Anyways, I am still cleaning out the system and fans about 5 to 10 minutes left. Thank you for the fast response I will definitely keep you posted.
