Hi tomsHardware-Community,
so far I was here merely as a reader and learner, now I got a serious issue with my GPU and thought this would probably be the best place to ask for help, because I've seen a lot of knowledgeable and helpful people around here. Let it be said, that I am no native speaker, so expect the one or other odd word. So in advance let me say thanks for looking at the issue at hand.
Current Rig:
Windows 7 64-Bit
Intel i5 3750k @ 2.4
Sapphire HD 7850
2x 4GB DDR3 Ram Kingston Hyper X
Asrock Z68 Pro3 Gen3
Seagate Barracuda 1TB
Sharkoon WPM 600
Issue:
So I bought the aforementioned GPU roughly a year ago to integrate it into my existing rig. At first, everything was fine and running great for maybe half a year ( not super sure ). After that time, I found that my Display wasn't always turning on when booting up like it should. After some testing I found out that everything runs fine and the pc is booting normally when turning on ( even the fans of the gpu ) except there is just no signal from the GPU. The internal graphics adapter of the mainboard however works everytime. ( Bios Settings are set to boot with the external GPU in the PCI-E slot. I also switched a few times from PCI-E to PCI to internal graphics just to make sure.)
When I would turn the pc on and off a few times it eventually would accept the Sapphire, that is, I would get a signal.
Now after this occured more and more I've done some research and found out that alot of people had this issue with the very same mainboard. I even found one official comment from asrock stating this would occur from time to time with some boards of this product line. So for me the thing was solved.
To not be without a computer for many weeks (I work from home and play games with this rig) I decided to buy a replacement board before sending the other in in regards to warranty.
I planned to have this board as a reserve later on. so I bought myself a MSI B75MA-P45. Today I got my new mainboard and just wanted to test it properly before preparing the package for asrock with the faulty mainboard. Guess what? Same issue! Internal graphics work, Sapphire doesn't. Checked Bios, settings are correct.
Now I asked a friend over with his pc. I swapped his Nvidia 650GTX with my Sapphire. And again his GPU doesn't work in my rig - the internal graphics do - and my Sapphire works in his computer just fine. So since 2 completely different mainboards got the issue but swapping out the GPU showed that it isn't faulty too, I guess that leaves only the Power Supply? 600Watt should be more than enough as far as I know and everything else works with the PSU. I have never heard of such an issue, where only the GPU doesn't work anymore. The power cable for PCI-E should also not be at fault here, as I have 2, one of them never used, and this second one also didn't work. What do you people think?
Sincerely
Chris
