USB ports not working

by evankli / October 15, 2015 9:35 PM PDT

All of my USB ports suddenly stopped working. I left my computer on sleep for a few days and when I came back my keyboard and mouse LED's weren't on. I tried different ports and none of them worked. When I tried replugging in the USB wires that go into the mobo, my mouse LED would flash for an instant and then go dead. Is there perhaps some type of problem with too much current going through the USB ports? My mobo is fairly new with not much use on it. I believe its a MSI Z97 gaming 3 or 5 motherboard.

Sleep is known for such things.

You didn't reveal if you did a full reboot.

Did reboot

I tried doing a full reboot a few times, someone told me to go into BIOS using the PS/2 port for the keyboard. Going to try that when I get home.

Are you telling me that your USB keyboard is working to get to the BIOS but it all fails in Windows? No, you haven't told me that yet so I can't guess what to do next.

If the ports did fail as you noted, then you would not get to the BIOS. Ya?

Sorry, I meant the USB ports don't work period. But someone told me that if i hooked up to the PS/2 port and try to get into BIOS that way it could help.

That's a good idea.

Yes I tried the ones directly on the motherboard as well as other ports attached onto my case that were connected through a wire onto my mobo

Let's hope for the best.

About all I didn't cover was a CMOS reset. Since you have little to lose at this point, use the CMOS reset noted in your motherboard manual.
