Vista - Comp doesnt read my usb keyboard

Well i use vista basic and this USB keyboard just wont work. Ive reinstalled the driver, system restored, but still doesnt. It was working fine for months , but all of a sudden today it decided to not work. Any solutions?

Keyboard has probably gone bad. Try another USB plug and try repeatedly pluging in and out. Sometimes a good reaming gets USB devices like keyboards, mice and scanners working.

Have you tried plugging it into another port? Have you tried the KB in another computer? This will ascertain if it is the KB or the port or something else....

Is it wireless? If it is change the battery.
If not try a different USB port on the back of the computer.

I will say this much, I had this kind of trouble on the ASUS P5N32-E SLI motherboard I had, with my Microsoft Comfort Curve 2000 USB Keyboard, thought it was the keyboard, but realized soon after getting my 975XBX2 motherboard back in March, that it was the motherboard causing problems with my USB keyboard. I'm still using my old, but reliable Microsoft Natural Multimedia Keyboard, which is a PS/2 keyboard

First try another USB port, if you still have trouble, then try it in another computer. If it still won't work, try new batteries if it's a wireless USB keyboard or try a new USB keyboard. If then you still have trouble, then you need to be willing to spend money for a PCI or PCI Express USB adapter, and finally if the USB card doesn't help, then you need to consider the possibility of replacing the motherboard.
