Keyboard crashes certain programs

[Zetriax]

I have an MSI A6300 with Windows 7 on it. I've had it for almost 2 years.
Whenever I use the keyboard in certain programs like windows explorer and some games, the progam crashes. Not all programs are like this, only certain ones. I can still use my mouse though.
How should I fix this? Is it time to reinstall Windows?

First attach an external keyboard and post if the problems remain. That will help determine if the problem is hardware (inbuilt keyboard) or software.

When the programs crash do you get a BSOD? If so, post the alpha-numeric string in front of the parentheses.

Yes, it still crashes with an xternal keyboard. The only message that pops up when it crashes is this:
