Random restarts on Dell with Windows 7, no BSOD

[Enuff]

I have bought a Dell and it has happens to restart at random times. It can restart while surfing the web or the kids playing a web based game.It will also restart when it is idle with the monitor off. This is my wife and kids' PC, I have one right next to it. I can hear it restart when it hasn't been in use at all.

I have ran Malwarebytes and all it found was a few registry errors I will post at the end but they were caused by Pup.LivingPlay. I have also ran GMER and it didn't find anything.

here are the specs for the PC

Dell: Inspiron 580S
Intel 5i 650@3.2 GHz
8.00 GB Ram
Win 7 Home Premium 64-bit

Turn off automatic restart by go into the Control Panel, System, Advanced System Settings, Startup and recovery, and uncheck automatically restart. Chances are good that the computer is still infected. If you still have problems, start a new post in:
