Hi. I booted my computer a couple days ago and my keyboard didn't work. The keyboard is fine, it functions well when connected to my laptop.
I have tried plugging the keyboard into all USB ports. I tried using the front panel USB ports. I tried connecting an extra USB hub.
I have reset the CMOS with the button on the mobo and also by removing the battery. Nothing changed.
My best guess is that whatever makes the USB ports work is toast. And being that I can't get into my computer there's no way to uninstall, reinstall, update the drivers or repair them from inside the OS.
Is there any way to make them work again? Mean looks, cussing at it, I'm willing to try anything.
Windows Vista 64 bit
EVGA nVidia 750i SLI FTW mobo
If you have another computer on the same network, you could try Remote Desktoping into it and uninstall/reinstall drivers if nikorr's recommendation is correct.
oh,,,i just remembered something ....sometimes Windows gets locked keyboard and you can press Ctrl t n l ie. keep the Ctrl key pressed, then press t and letgo, then press the n key and let go and then the l key
USB was enabled in the BIOS. I didn't enter the BIOS and change anything before it quit working.
After I reset the CMOS, when I power on my computer the boot screen comes up, there's a message that checksum values have changed, and I have the choice to press F1 to continue or delete to enter setup. However since my keyboard/USB ports aren't working, pressing F1 or delete does nothing.
I did consider remoting in, but I have that disabled.
Solid. I'm in. Bought a USB keyboard with a PS/2 adapter (the only pseudo PS/2 keyboard in town). Just fired it up and am able to navigate and select items in the BIOS. So, now to check the BIOS settings and then see what the device manager says about my USB ports.
There was no USB functionality. I have 2 USB keyboards, one wireless and one wired. I have 2 wireless mice. The BIOS and windows did not recognize them or recognize that they were plugged in. There were no yellow triangles in the device manager (even after scanning for new hardware). The only device that I could use was the PS/2 keyboard.
I replaced the motherboard, all keyboards and mice work with the new board.
