Recently built a computer with the Asus z97m-Plus motherboard running windows 8.1. Everything worked for about a week. Woke up this morning, all USB ports do not work.

The USB ports (keyboard and mouse) work fine in the BIOS, but once it boots to window the lights turn off on my mouse and the keyboard as well as the other USB ports stop working.

I've ordered a cheap PS/2 Keyboard in order to get into the computer but in the mean time what are some things I can try to fix it?

SPECS:
CPU: i5-4690K
Motherboard: Asus z97m-plus
GPU: R9 280x
RAM: G.Skill 1866 CL 9 RAM
PSU: EVGA Supernova NEX 650g

Things I've attempted:
Unplugging and holding power button for ~1 minute.
Disabling xchi mode
Disabling each individual usb port then re-enabling.

Thanks for any and all help!

Had the same issue on my windows 7 Home pc with same CPU and MB. All this happened right after I installed the Intel chipset drivers on the MB CD. Found an old PS2 style mouse. Plugged that in and rebooted. Windows recognized it. With a mouse now working, I logged in by clicking on the funny icon in the lower left hand corner. This allows you to display and on screen keyboard. Login using the onscreen keyboard. Now that you're logged in right click on my computer and go to properties. From there click on device manager. Expand the USB section in the device manager and uninstall all of the USB controllers. Don't worry about the Hubs, just uninstall the controllers. Make sure to check the box "delete drivers from disk" or...

You say it works in the BIOS but turns off sometime during Windows bootup? Have you tried seeing if say they work in a bootable copy of Windows or Linux? It almost sounds as if the Windows USB driver got corrupted somehow. I've had this happen after installing the AMD Southbridge driver on a windows 7 system. If the driver isn't functional the lights on your USB devices won't turn on as power won't be supplied.

Hmm don't have one right now as I'm off at college, I figure if the USB ports work in the BIOS but not once windows boots, its more of a software / motherboard problem though.

I agree.
Try loading an earlier Restore Point:

1. Create a new SYSTEM RESTORE point, then

2. Load the first restore point BEFORE your problem started.

Can now confirm that my keyboard and mouse work on Linux (Ubuntu), so it is most likely a windows problem. Will probably be able to fix after my PS/2 Keyboard comes in.

Open to any other ideas too!

I have the exact problem on a Win 8.1 Dell Inspiron, after a reboot today all USB ports stopped working. But in the Bios everything works.

Wonder if it was a Windows Update that killed it. No idea to revert it as without a keyboard I can't get into recovery mode using shift-f8

Make sure to check the box "delete drivers from disk" or something of that nature. Then have windows rescan for changes and everything will come back to life.

Hope this helps!
