PC shutting down as GPU reaches 80°C

[Cyberuben]

Hi,

For the last few days I am not able to play any games. I thought it had to do with the weather (26°C), but while I was playing BF3 my PC randomly shut down. I started it back up and thought it was a power failure. As I joined the BF3 game again, the same happened, my PC died after 5 minutes. This time however, it refused to start up for the next few minutes.

Now I was playing Banished today, and I saw my GPU temp slowly climb up to 81°C. At this temp, the PC shut down. I restarted and checked my temps using Open Hardware Monitor. My CPU temp is roughly 40°C and I doubt this is the problem.

The GPU I have is an XFX Radeon HD7970 3GB Double Dissipation edition, and I do not have GPU Overdrive enabled in AMD overdrive. I noticed, however, that the speed of my fans do not even get to 100% before my PC fails. In the past I have seen temperatures above 80°C and it did not shut down my PC, but BF3 always caused my GPU fans to run at 100%.

I read multiple websites where everyone puts the PSU at fault but I simply don't see how it runs for a couple of seconds and then stops running. My PC worked just fine a few weeks back, I have been away for 12 days and when I came back I only did some programming, no gaming. The situation or place my PC is located has not changed so I doubt this is the cause. I have a case with 4 fans blowing air in and 2 fans blowing air out. My CPU (AMD FX8150 @ 4.1 GHz) has a Scythe Mugen 3 cooler. I checked all fans (CPU, GPU, PSU) and they are all spinning. The GPU and PSU are barely a year old so I guess it is covered by warranty in case it is at fault.

I have an XFX Core Edition PRO750W power supply, I guess that is important information aswell.

How is your motherboard temperature when you are playing while your GPU is 80 degrees ?

My Mobo shows 2 temperatures. I started the game and shut it down just before it'd reach 80°C and my motherboard temperatures show 52°C and 37°C max. They are that temp while idle and under heavy load and I must say I barely ever saw them higher than those numbers

I just started Banished while having Catalyst Control Center open. The Core clock immediately jumps to 925 MHz, and Memory clock jumps to 1375 MHz (according to the store I bought it, this should be 5500 MHz, or is this peak?). Either way, the load goes to 100% and it starts heating up rapidly. Even manually setting the fan to 100% before starting the game and leaving it like that won't help. It'll reach 80°C and power cuts off.

Can i get your system specs?
