[SOLVED] Pc won't boot

[Heinrich87]

Hi, when I try to start my pc it just shows an American megatrends screen and it says:
USB devices total: 0 drive, 0 keyboard, 0 mouse, 0 hub

Detected ATA/ATAPI Devices...

USB Devices over current status detected!!
NO keyboard detected!
System shutting down in 15 seconds!

I was playing CoD, and punched my keyboard, and then my mouse, and keyboard stopped working. I turned the PC off and on again to see if it fixed it, but now im just stuck at the American megatrends screen.

Please, help!

I tried my friends keyboard, and it detected it, but it still says 0 drive, and 0 hub... And wont boot
