I’ve been trying to solve this for two months now, basically the computer that’s broken had windows 10 on it previously and I started getting a black screen within 5 minutes of log in. I couldn’t even open a windows installer for a format or anything, so I used another computer to format the hard disk. There was no problems up to this point.
When I plug in the hard disk and put in the windows 7 installer disk for windows 7, I can’t download it as my keyboard or mouse aren’t being detected or anything. They both light up but neither respond (when pressing numlock on keyboard the led doesn’t light up). I’ve tried 3 different keyboards, 2 different mice and still nothing. And no, I can’t even get into bios or anything like that. I’ve also tried putting it into usb 2.0 ports and replugging them in whilst I’m in the setup, as well as replacing the battery. I’ve had this problem for 2 months now.
Motherboard: Gigabyte GA-78LMT-USB3.
