Windows 7: Keyboard doesn't work, then mouse begins losing function

Keyboard doesn't work, then mouse begins losing function

Recently I've come across a situation where my computer will boot with no keyboard function. I cannot enter bios, boot in safe mode, etc. However, upon Windows 7 loading I have full function of the mouse. That is until I hit any key on the keyboard, then I lose left click function only. I can still move the mouse, I can still right click with the mouse. I also noticed that caps lock and number lock did not work either.

I figured that maybe the keyboard was bad and so I plugged in a different brand new keyboard and booted up the computer. Everything worked fine. The keyboard worked flawlessly, the mouse had no problems at all.

Restarted the computer to install windows updates, and upon the next boot I once again was left with no keyboard function and then once again no left click function.

These problems only began after a program was uninstalled due to it freezing up during use. (The program was a puzzle game that was purchased and installed from a reputable game website)

I am at a complete loss, and I cannot tell if this is a hardware problem or a software problem or even a virus problem.

Both the mouse and keyboard are USB. Other USB devices work fine, including a headset, a printer, and a scanner.

Any help is much appreciated!

Thanks in advance.

If it was my computer I would Go back to a restore point before you loaded the new puzzle game.

Then do a sfc /scannow and see if Windows system files are still working properly.

Some tutorials by Brink to help you.
