Sudden Graphics card performance drop

[gabbers56]

I recently moved to a new place. When I plugged my computer back in the resolution was all messed up. I went to the AMD Radeon settings, but when I clicked on it a error message would pop up. I decided to uninstall and reinstall the AMD drivers, and afterwards it worked, but now all the games I played on high to med settings i can't play because my card can't even handle low settings anymore.

Graphics Card: XFX Radeon R9 280X

Did you maybe plug the video cables to the motherboard when you hooked things up again?

Turns out my cpu fan was loose.
