Hi Daniel
There may be a problem on the motherboard, because you cannot get into BIOS and also that one of your USB ports is experiencing an over-current error.
Disconnect from the mains electricity.
Press and hold the power button on the case of your PC for 30 seconds.
Wait 10 minutes
Reconnect your PC to the mains electricity
Start your PC, if you cannot boot int BIOS or Windows, then you will need to take your PC to the PC Repair Shop to get the hardware tested on a bench.
