PC Rebooting Itself

iLuXiR · 24 Jul 2009 at 21:11

Hey guys, Well i've got this annoying problem where my pc just reboots itself while playing in game. I can play for about 30 minutes before it reboots sometimes less or more if im lucky. I've had this problem for about a week i've had this computer for about couple months now with no problems. I tried cleaning the inside of the pc and cleaning all the fans but that didn't work out so im not really sure what else I can do to sort this problem. Any help would be appreciated, Thanks in advance

Did you try diagnosing the memory? Download and run Prime95 and run torture test to see if it detects any problems. You can also try memtest86. It could be the power supply as well, how many watt is ur power supply and which manufacturer?

yea, what psu do you have?
also as Fahim suggested run a prime test and do a memtest overnight.
could also be overheating, what are you temps?

Download HW monitor to compare temps.

Your northbridge seems fairly warm.

.. which make? A decent 420W is completely different from a generic rubbish 420W.

I'd bet on the PSU being the problem as well, if your ram passes memtest then definately considering upgraing your PSU.

Well i ran the memtest and about 10 minutes in my pc rebooted, the same happened on all three torture tests.
