Hi there, I seem to have a little problem with my mainboard but I think it’s important to tell you what happened before first (you may skip this part):
Yesterday I finally got myself to do some cable management and dust cleaning on my till then working PC. Pulled any cables out, took the mainboard out, installed a backplate, put the mainboard in again, plugged any cable in in a way that it stays on its path, and closed the PC again. So far so good.
However, when I tried to turn on my PC it would just stay on the "press F2 or DEL to enter bios"-screen forever. No post, just that screen.
