PC Problem- Restarts

[Swafe]

Hi guys

Got a problem with my PC that REALLY annoys me

When I turn it on from cold, itll just randomly turn off for no reason after 10 minutes, but then, if i turn it off and on again itll be fine

I first thought it was a heat problem, as it was running very hot, but it cant be. Ive tried it with no case on and it still does it after 10 minutes, yet if I then restart it, even if its crunching UD all day, it wont reset, even if I have it on for 10 hours.

So is it a problem with my motherboard? It seems to be almost timed to 10 minutes to annoy me but then its fine unless I leave it off for a couple of hours. I've honeslty no idea whats causing it, and even though it runs hot, it cant be the heat due to the patterns of how it does it.

I had that until I updated my version of Catalyst.

Only other thing I can think of is the temp. until I reseat my heatsink I can't use my PC in this weather.

Its not catalyst, Ive been using the same drivers for about a year with no problems, until now
