I have a custom PC that recently crashed and needed a windows reinstallation. Ever since windows was reinstalled the USB ports have not worked. The computer does not detect the USB ports in the device manager. What should I do?

Thanks a Gigalot!

    Did you install the motherboard drivers from the manufacturer??  depending on the system and the OS, you may need those for USB to work.

    I support what AlbertaBeef had to say and just wanna add that if you are running Windows XP, then loading Service Pack 2 will probably give you the correct drivers to get your USB ports going.

    If you are running older Hardware and an OS before XP then AlbertaBeef should have nailed the problem for you.

    I any of the above don't work, try clearing the cmos or if you are confident enough update the bios to the latest version.
    Only go to the bios flashing option in last option cause with a bad flashing the Mobo won't boot at all.

    I once lost my usb ports and the only way I got them back was by flashing my bios.
