PC not posting with GPU installed

mattjm · Jan 9, 2014

Hey guys,
I was testing my PC today for memtest errors. After that, I installed both the sticks and reinstalled the case fan and tried to run the PC but it is not posting at all. All the fans run and the case's power LED works but pressing the power button in the case doesn't turn off the PC, instead I need to press and hold for that to happen. This had happened a couple of times in the past, but reinstalling the GPU used to work. This time trying even 10 times didn't work.
Removing the GPU and connecting monitor to mobo's port works and the PC boots. Is it possible that the GPU is dead? Any solutions for this? Posting this from phone. So, please ask if more details are needed. PC is in specs. Thanks.

PCIe power connectors hooked up to GPU, and EATX +12V 4/8-pin power plugged into motherboard? Situation you describe is typical of GPU not having enough power and overloading PCIe x16 slot as a result.

Observe the slot for debris, and also take a pencil eraser and very delicately polish the contacts on the video card. Because re-inserting it in the slot worked in the past, I suspect there may just be a connection issue.

Thanks for the quick reply guys.

I checked the power connectors of mobo, CPU and GPU. All seem to be good. However I had forgotten to mention that the 24 pin power connector had gone loose when I was reinstalling the fan. So I guess something else mght have gone loose too. What could it be?

Regarding the debris, I cleaned the slot and the connectors for dust and looks like the last piece of gold colored connecting point has worn out. To be clear about that, I'll post a pic as soon as I get hold of a camera.

Update: The display showed up once. But it was garbled. The GPU was giving output only through DVI. There was no output through HDMI. No display after that though.

The below pics show the contact points that seem to have worn out. Sorry for the horrible image quality. That was the only camera that I could get.

That on your card looks pretty normal, I think all cards have shortened pins on the end. It does sound like power, but it could be a dead gpu. Try the card in another system or try another card in your system. Hopefully you can find a computer with which to do that.

Sounds bad. My best bet is that the GPU is dead.
I have been wrong before however, trying another card in your system is good advice, do that first.

Thanks.

The garbled display I mentioned earlier was completely garbled. It was a white screen with some thousands of blue dots all over the screen. Nothing else.
The only desktop near my place which has a PCiex16 slot is my uncle's.
The PC has Intel Pentium G645 and Gigabyte B75M-D3H. However, it has a small, old micro ATX case. So, not sure if 5770 HAWK will fit in it.

Another thing is that his PC runs an age old 400W PSU. I surely won't power my GPU from that PSU(it doesn't have PCIe power connector anyway).

So, would it be okay if I supply power to his motherboard and GPU from my PSU from outside the case by keeping the PSU on the floor or a table and the rest of the components will get power from his PSU mounted inside the cabinet?

PS I read from the guru3d review of my card that it has points to check voltages of GPU and memory. Does it help in anyway in determining if the card is dead or not?

This card will also have voltage checkpoints so you can check GPU and memory voltages with the help of a multi-meter.

PPS Did the voltage reading and found that the GPU is drawing about 1.25V and memory, about 1.65V. Does that help in anyway?

You could get a indication that the card is not working right, but you can't prove that the card works. So it would leave you none-the-wiser.
No idea what the values are supposed to be, sorry. You really need to test the card on a different setup. You won't be sure, before you do.

Fumbling around with your uncles machine, sounds like a bad idea, don't bother.

You sir, need a friend

Ha ha. None of my friends has a desktop, at least one with PCIex16. They are all laptop users. Moreover, I have some serious health issues now. So, the only place I can really travel to, that has a dekstop with my health condition is my uncle's

So guys, I want to make sure that it's my card that has gone bad and not the motherboard's PCIe slots. (The PC has been working fine on onboard graphics) My board has 2 PCIEx16 slots (supports crossfire dual @ x8). Inserting the card in the second slot didn't work either. Does it confirm that the card is dead and not the slots on my mobo or do I need to waste my money on a cheap card for testing?

If the card's dead, I might get an R9 270X when I recover and get back to work. But that'll take some 2-3 months. I'll open a separate thread at that time.
