PC does not boot with graphics card

piratos · Jul 15, 2015

searched for but I couldn't seem to find someone else with the same problem as mine, so here goes:

Graphics Card:
ATI RADEON HD 7950
PSU cooler master v1000
I connected the graphics card via a PCI-E 6 pin connectors from psu but PC does not boot
when changed graphics card with hd 7870 xt everything works

and When I unplugged the power (PCI-E 6 pin connectors) from the card 7950, but leaving the card on the motherboard, the computer boots perfectly. but black screen
Is the issue the PSU? or graphics card?

Happy to provide more info if you need.
Thanks in advance for any assistance!

Sounds like a PSU issue because when it isnt supplying any power to the GPU, it boots but with a black screen. Try powering on but with the monitor connected to the onboard graphics, but still leave the GPU in the motherboard. See if it boots. Also try using a different PSU and see if that solves the problem.

What do you mean when it doens't boot? It's just a black screen, but the fans are spinning? or literally nothing happens when you press power?

When I first turned on my computer, everything seemed normal except the fact that I had a flashing black screen. I was freaking out until I figured out the HDMI cable was loose. xD

Maybe make sure your gpu is firmly in the pcie slot?

Seems like the GPU is your problem. Try testing it in a friend's PC.

celtic_warrior99 · Jul 17, 2015

Either slot pcie 2.0 or 3.0 will work but I suggest you follow the above advice and test in a friend's PC.

celtic_warrior99 · Jul 19, 2015

What do you mean by VRM?

piratos :

Are there any burnt marks on or around the VRM area?

I had to update my bios for my computer to accept my new graphics card.
See my last post in this link for slightly more details. http://www.tomshardware.com/answers/id-2603465/gtx-970-buy.html
Sorry for few details. I'm using chrome remote desktop from my phone.

Edit: Typo
