Hey all
(newonforum)
So i have had this problem with my GPU (XFX HD 7950) (atleast its where the symptoms are) for the past tree weeks. Its a problem that annoys me quite a bit and limit my experience within my computer.
The problem is that whenever the card reaches 72-75 celsius during when i play or during benchmarks, my pc just turns off without warnings. It just "dies". It wont turn on again unless i turn off the PSU (Corsair TX850) and empty the power circuit by holding the power button in 10 seconds. When it turns on the Graphic card fans spin at max and i dont get any signal to my monitor even though i can hear windows booting through my speakers. I must then restart the pc in order for it to boot normally, but sometimes it says that windows couldnt boot properly and leaves me on a screen where i can choose between booting windows normally or do startup repair, but my keyboard dont work during this screen.
I recently reinstalled windows 7 ultimate and fresh drivers but this didnt seem to fix the issue. I also clean my pc every week and the gpu invidually sometimes, and i have 7 case fans so my pc is well ventilated.
I think the first time this happened were after running furmark benchmark, but im not completely sure. I also have made sure the 6-pin and 8-pin sits firmly in place. Ive also tried to run the fans on the gpu at 100% with my windows open while running unigine valley but it still got to 72-75 celsius and died.
Ive been quite frustrated over this problem so i appreciate help very much as ive tried to reach out for help on other forums without any luck.
Thanks in advance
