I bought a new psu, cpu cooler and gpu. I'm still waiting for the gpu to arrive, but in the meantime I decided to open the case and change de psu and cpu cooler. I took everything apart, installed the psu in th case, took out the old cpu cooler and put the new one (with some difficult). Then I put everything back on and tried to boot.

The first time I let the gpu outside to see if everything was working, but I forgot the sata power cabels lol, but in the second try it worked. no problem

Then I unplugged everything, put the gpu in the pci express, pluged the psu cable and... nothing... Tried to restart several times until my Windows actually crashed and restored to a primitive state. When I decided to just use my onboard graphics to look on the internet for help I realized that the audio drivers where missing, so I suspected that the Motherboard might had hard reseted or something.

I run the Display Driver Unnistaller on safemode and excluded the amd files but the pc still doesn't recongnize that there is a gpu on the pcie slot.

I'm not really worried about my gpu, I'm more afraid that I might had damaged my pcie slot and my new GPU wont work or something.

I guess I could try to reinstall windows but my internet isn't very good. Having to redownload Witcher 3 would kill my vacation t.t

My motherboard is a ASRock B75M-DGS R2.0, my GPU is a HD 7770. I could try to run the gpu cdrom, but for that I would have to put the cd rom reader back on my computer.
 
Sorry for the triple post, but I managed to make it work.

I opened the case put my cd reader and changed the pcie power cable (it is only one, but it has two 6 pin headers), put the cd in and didn't even need to boot, the gpu was already working. My question now is my cable malfunction and should I replace my psu? Or it is working as intended aka the secondary cable will only work if the first one is connect. Or maybe it worked because I put the graphics card cd rom?

My psu is a XFX TS 650w Bronze series
