Pc keeps restarting

I've done all that crap and nothing got picked up !

--So you ran

Process Explorer
TCP View
Hijack This or Startup List and nothing got picked up and you did not see anything suspicious. Is that correct?

So, you also checked the System Log and did not see any Errors?

Theres the HijackThis log, nothing unusual

I found this article on ComputerHope. Read the article and see if it makes any sense.

I hope you ran HijackThis with System Restore set to OFF.

I did not find anything suspicious, except for *BestPopupKiller.exe*. This product is from swanksoft.com which was listed under Rogue/Suspect Anti-Spyware Products in the link below.

Try un-installing BestPopupKiller and see if you notice any difference.

pauljc, nothing looks suspicious in the log file and at this point I have nothing else to say. Let's see if others can come up with any creative ideas of solving your problem. If I come across anything else I will let you know. If you do solve on your own, I would definitely appreciate what/how you did it.

bestpopupkiller came with a program called Spy Killer, all my scanners aint picked it up and it does its job, its fine i think.

Try the option of Rebooting and Enter into CMOS as described in the ComputerHope article <Issues With Operating System> and lets see if it is something OS related issue or not.

Like ive said, it only happens when i do multiple tasks or a big game etc, so it wont do anything in the CMOS
