So I had my computer shipped from Germany to the US as I was relocating. On receiving the computer I realized that the Deutsche Post completely bashed the back of my computer. This knocked out my GPU, other than that nothing looked damaged.
I bought a new case, put everything back together and started the PC up. It showed a great amount of pixelation and tearing. I started it up again and same result... after several attempts the tearing was gone and it booted with no issues. Upon starting a game, watching an HD movie, or starting furmark the screen would pixelate and tear and if I didn't stop whatever was causing it the display would trun solid windows xp blue and I would have to hard reset/shutdown.
I instantly assumed it was the GPU so I ordered a new one. Now my friend claims it may be the PSU failing on me. Because of this my friend allowed me to try and use my GPU on his computer to test it. It would display solid xp blue and the cursor all attempts besides one, which displayed the windows 7 loading screen then again, blue with cursor.
What do you guys think? GPU or PSU?
OS: Windows 7 64bit
PSU: 650W Antec
CPU: Phenom 955
GPU: AMD HD 6850
Mobo: Crosshair V Formula
The GPU does take quite a bit of power, however, when the PSU fails it generally fails to a degree that nothing works properly. I've never had a PSU 'die down' and lose only 50-100 watts. It's always been complete failure. Also, when will your new GPU get there? And the last thing I can recommend is run benchmark tests for other parts of your computer, if it only crashes for the GPU and not, say, the processor then you know for sure.
Okay so i just ran a stress test for 10 mins on my CPU (prime64) and nothing went wrong, low temps and no crash). As for it being my slot, i tried a pci-e x1 on it and it worked fine, on top of that when it was tested on my friends computer we knew that his slot worked since he had been using his gpu with it, and continued to after the test.
Thanks you guys, feel way better now. The prime64 test is so obvious to me now xD
