Ok, so I tried to change the PCI settings to enable 4 or more GPUs, but it seems that every time when I boot my computer, I get to see a blank screen after POST. No Windows logo and I also tried to reinstall Windows, but it somehow crashes I think... Any suggestions? Should I change my bios to an older version or did I miss something?

Edit:

Oh wow! I didn't know that multiple people have the same problem:

Is there no solution to this??
