Keyboard is glitching in Windows 7

I am having an issue with my keyboard, sometimes for no reason at all the keyboard will glitch and start typing qwertyuiop[]\asdfghjkl;'zxcvbnm,./`1234567890-= no matter what key I press. I have tried updating my chipset drivers for my USB port, and it solves nothing. I have even gotten to the point of buying myself a new keyboard and even that doesn't stop the problem. It is getting on my nerves already, any help would be appreciated.

Sorry for the delayed reply.

Was this/ is this a new problem?

If so have you tried a System Restore to a point prior to your problem?

start > All Programs > Accessories > System Tools > System Restore
