Probably you either damaged something or some connection is loose.
If you can't find it yourself, and your local tech can't either, the most likely solution is a new motherboard.
Ok so recently my power button went into my PC and it broke. So I went into the mother board and jumpstarted the power with a screwdriver. I did it but none of my USBs are working and it's not doing the normal thing it would do when I would turn it on. All it does is turn on and nothing else. Could somebody pls help?
