Random restarts?

[Cameron146]

Recently my computer has started doing the occasional random restart. It just did it for the hird time in the past few weeks. Does anybody know what could be a potential cause of this? I've scanned my computer and no sign of any viruses or malware. Specs Below

AMD FX-4170
AMD Radeon 6770
4gb Dual Samsung DDR3 Ram
ASUS M5A78L-M
600W Quiet 80 plus quad rail PSU

Have a look in event viewer,It's normal to have a lot of warnings & errors so best look at the event viewer immediately after the problem occurs,then check if anything is logged for that particular time.
Go to control panel(All control panel items)/performance information and tools/click advanced tools on the left hand side/view performance details in event log.
this will take you to diagnostics-performance & boot /shut down events,It may or may not give a clue to the problem,but worth a try.
If nothing obvious showing there,at the top of the tree on the left hand side,click on custom views/administrative events.
You might get more information that points to something by selecting details/Friendly & XML view,in the event viewer.you could also try selecting "event log online"at the bottom of the page
