Computer restarts when playing demanding games (HD 7970)

Hi, i just got my Sapphire HD 7970 Ghz Vapor-X card, but when i play demanding games like BF3 and Far Cry 3 that computer just restarts itself after abt 30 minutes. I dont get anymessage or anything. Anyone got an idea?

I tried most things:

cleaned old drivers
updated bios
tried newest drivers
removed my cpu clocks
ran memtests
contacted sapphire support
contacted reseller support
checked my temps (no probs)

Intel Core i5 3570k
MSI z77a-g43
4 Sticks RAM (total 8gig)
1 SSD
1 HDD
630watt powersupply
Sapphire hd 7970 ghz vapor-x

  1. download http://event.msi.com/vga/afterburner/download.htm

    and let us know what temps u getting, also what kind of powersupply u have?
  2. I've already checked my temps, they are around 60 in full load, i got a silverstone 630w, non mod.
  3. Hmm, that's really odd. I would suggest maybe a reformat as that normally fixs things.
  4. Well first what you may want to try to do is turn off the automatic reboot it could be BSOD but it set to reboot instead.
  5. have u scandisked ur hdd and selected fix errors automatically, also defragment ur hard-drive and run cccleaner to clean ur registry?

    those tips always help usually.
  6. CPU temp could be an issue too, check it just to be sure.
  7. those temps are fine, ur gonna worry when full loads at 80+ degrees celcius but 60 full load is nice :)
