I built my own pc a while back, basically tho now I’m wanting to sell it so I was doing like a factory reset to delete everything and reinstall windows or whatever, however since if done my reset my pc just turns on and that’s it, my mouse doesn’t get any power from any USB ports only my keyboard, I can’t enter the bios or anything because i won’t even get that far it just runs on and on but does absolutely nothing and was fine before I did this. There’s no display and I’m pretty stuck as what to do. Any help would be much appreciated.
