Broken GPU? Blackscreen after Windows 8 logo, artefacts in bios

Hello,

My problem is as follows. I was problemlesly playing on my Radeon Sapphire 6870 card, when out of nowhere the PC froze. I had to manually turn it off and when I tried to turn it on, I got a black screen after Windows 8 loading logo (circle). Same with Windows 7, only there it was after login. (I have a dual boot).

I am currently suspecting dead GPU because of those reasons
- I have artefacts in BIOS (I don't have them with integrated MB card)
- After windows 8 reinstall I was able to run the system for a bit but then it crashed (screen full of blue sqaures - NOT bluescreen of death) and returned to same scenario (logo, blackscreen)
- The system runs without a problem on the integrated graphic card.


I was thinking that if not GPU it could be PSU (even though I have never had a problem with it before and I am using a SEASONIC one) but that probably wouldn't cause the artifacts in the bios and wouldn't be so abrupt.

On the other hand I was able to install the windows with the GPU and it ran okay for a while. Wouldn't there be artefacts during the instalation or shortly after if the GPU was faulty?

I do not have means to test it on other computer.

Thanks in advance

These point the conclusion you suspected. The GPU. The PSU couldn't cause artifacts.
The artifacts appear after the GPU fails.

Out of curiosity, how is it possible that the artefacts (rows of pink dots) appeared in BIOS but not during the Windows installation or loading screen?

Ok, I did some research and it is possibly not the GPU.
The suspects are:
PSU
GPU
Mobo

I am looking this up on other forums and sites and trying to find a fix.



OK, so how we diagnose this is replacing parts. Can you replace any of the parts listed above?

Sadly I can't. Everyone else I know has laptops.

Not much of a way to repair this then... Not unless you can switch the GPU or RAM. You can get Memtest 86+, put it on a USB, boot from that and run the tests. If no artifacts come on that, then we know it is not the HDD and the GPU. If the test shows no problems, that the RAM is out of the question. Time to get a new laptop. If it shows signs of a problem, then the RAM is at fault and you need to replace it.

I don't think it's a ram or HDD since right now I am running the system just fine with the integrated MB card (HD 4250). However when I switch back to the 6870 it loads the window logo but then goes full black screen.

So my guess is MB (something centered around the PCI slot) or most likely the GPU.

Technically laptops don't have PCI slots. buT

Ok, enough of the technical crap. Is there any way you can switch the GPU out? I know some laptops allow this.

It's not a laptop it's a desktop. I can't tell someone to test my GPU because everyone AROUND me has laptop. I have removed the GPU and the PC runs fine on the integrated GPU. Sorry if I didn't say that clearly.

Ah. Sorry, my bad. Can you order a very cheap GPU and have it shipped to you quickly? There is not a way to replace the mobo. And noone can lend you a GPU.
