PC crashes while playing a game

Hello,

I used to play games, and sometimes, the game would freeze and my screen would go green/purple/pink/yellow/others, but recently, like starting tonight, each time I get into the game and start playing for 30s-2m, the game freezes and I get the colored screen.

I changed the heatsink of my CPU tonight, so could it be a loose connection when reconnecting some cables ?

Average GPU Temp when PC Crashes: 80*C

PC Specs:

CPU: i7-2600k
GPU: Radeon HD 6970
Motherboard: G1.Sniper2
Power Supply: Corsair AX 1200W (Yes, I know, overkill :P)

If you need any other specs, just ask.

Thank you.

  1. system specs please?
  2. I edited my first post to add them
  3. when you changed the cpu heatsink, what kind of heatsink did you use? also did you clean and reapply the thermal paste correctly?

    also, have you blown the dust out of your gpu lately?

    Yes, I changed cleaned and reapplied the thermal paste, and I now use a Noctua NH-D14

    I have blown the dust out of my GPU about 1 week ago.
  5. sounds like your gpu might be dying.
  6. Is there any way of knowing for sure it is the GPU ?
  7. swapping it out with another one would tell you for sure.
  8. Worst case scenario...

    your CPU cooler just added 2.7 pounds (or 1.2 kg) of strain to your motherboard which was damaged by the extra weight... a damaged motherboard is now damaging every component.

    It can happen, and avoiding the extreme weight and strain is the major reason to buy a closed loop liquid CPU cooler over an air tower. Or, you might just have a dying GPU. It happens.

    I'll change GPU's first to see if that is the problem, and then if it isn't , ill see about the motherboard.

    Thanks for giving mew that link.
