Usb ports not working

[Buntty]

Hello everyone

i was on my computer today and my mouse and keyboard were working( connected wirelessly through a usb)

My pc stopped recognizing my iphone thru itunes so i restarted my pc and now my usb ports are not working so i cant get past my login screen

I tested the mouse/keyboard on a different pc and they seem to be working and i would connect my iphone to my pc and it wont recognize or begin to charge either but on my other pc it will

any suggestions on what i should do?
is my usb ports fried or something?

thanks in advance

Sorry to state the obvious but did you try to unplug blow out (use a can of compressed air to blow out dust in the USBs) then replug after windows starts, it's worth a shot

Try resetting the BIOS back to default. If it still doesn't work, then you've got a corrupted BIOS or bad motherboard

Like masterasia said, you'll need to take Bios back to default.

Trying clearing CMOS. (Take out the battery on your motherboard and unplug your computer for the outlet. Wait 20 minutes, put in the battery, and plug it back into the wall.)

If that doesn't work, then again like masterasia said, the Bios/mobo is dying.
