Random AMD Northbridge error?

[iRileyx]

So my computer has just randomly powered itself off and back on, no warning before hand, just scrolling through youtube subscriptions when the screen went off along with the lights on my keyboard/mouse and then it restarted. It'd been turned on for less than 30 minutes before this happening.

 

First thing i thought of was to check the system event log to see if anything was showing in there.. and this is what i found.

 

I'm thinking its most likely a cpu fault, its not running "overclocked" at the minute but i do have it set to 3.8 with turbo disabled, but the max for turbo is 3.8 anyway. Its also the first time this has ever happened.

Or could it just be a random crash and everything is fine?

I don't know what it is but........ got any cooling blowing across it? information passing creates lots of heat.

specs/how old?
