CPU(?) not detecting GPU

Hello!

 

This is quiet a story, lets start with some background information:

My friends computer transported in a car for about 10 minutes, and the computer were working great until he arrived at his destination.

The PC did not detect the GPU in the PCIe x16 slot, so we moved it down to the PCIe 2.0 x8 slot. PC turned on, and it seemed good.

After a while the computer starts lagging, and we can see the PCIe utilization drop from x8 to x4 under load using GPU-Z. We deemed the GPU and the x16 slot damaged, only to find out, other my GTX780 did the same...

We moved the GPU to my rig(see profile for full specs) and both GPU's worked flawlessly. Then we stripped it thinking the case had a short somewhere, same problem, so we moved on and swapped the motherboard.

We swapped for some ASRock board, no GPU detected in any slots.

Swapped to a MSI board, no GPU detected...

Swapped to a Asus board and a new PSU, no GPU detected...

CPU works flawlessly with onboard graphics.

 

CPU: Intel i7-2600 (non-K)

 

 

Is it possible that the CPU is damaged? It seems weird since the problems started after the transport... Before anyone starts asking what cooler it uses, its stock.

 

If anyone has _any_ advice, we'd love to try anything that does not cost to much :)

That sounds unlikely... But that sounds like the only explanation....

What CPU is it that you are using? Have you tried booting with the CPUs onboard graphics?

I'm a noob at this but I would try swapping every component possible. Like swap out ram, swap out storage... Etc.

I love computer hardware and feel free to ask me anything about that (or phones). I especially like SSDs. But please do not ask me anything about Networking, programming, command line stuff, or any relatively hard software stuff. I know next to nothing about that.

I forgot to say that it is an i7-2600.

 

Works flawlessly with onboard graphics.

 

The rest of the components are swapped, Motherboard, RAM, PSU, GPU, HDD/SSD and tried it with and without the case.

Do you have another CPU you can try? If not, I don't think I can help you much more... I'm not exactly a pro at this.

I think that the GPU got damaged while transporting the PC from all the vibrations & bumps (if any). That's why you should unmount the graphics card while transporting your PC. I have read somewhere on this forum a story like this one, in which the graphics card (or even the PCI slot) got damaged by transporting the PC from one place to another

I dont, sadly.

Ye, but the thing is that the first PCIe slots on the motherboards we've tried wont work, so its definitely not a motherboard problem. I always remove the GPU during transport, but he didn't. The weird one about this one is that the GPU works, and the PCIe slots work too(contacted the store which tested 2 of the motherboards that was returned). There is a problem finding motherboards for this socket which is not too expensive here in Norway, considering its an old platform we don't want to spend too much on the motherboard.

 

Its tempting to just make him buy a motherboard and RAM for S-1150, then he would get the G3258 I got until he can buy a new CPU.

Seems like its the CPU, weird, but okay...
