Hi Guys am a newbie to the forum and i thought i start with a hum dinger for you, the random restart

I'm well aware you need loads of info to diagnose this issue so i'll post what specs i think you'll need then repost whatever you ask for..

I've used sandra to get ll the info so it should be ok i think...

Updated all drivers

This pc was a fresh install yesterday as Norton decided he wasnt going to let me use net no more, so i looked at my desktop n thought "time for a format" (as ya do) fully formatted n reinstalled, started to load up world of warcraft and randomly between 5mins and 1hr get buzz then a restart, initially thought it was WoW but then noticed if i do anything excessive really it forces restart, havin a serious head scratch wi this one and would appreciate any valuable input as to wht to try next, any logs you need just gimme info how to get em and i'll repost, i've used the site for a while unregistered to analyse probs of friends etc but this one is seriously checkin the stability of my brain...

Thanks in advance..
