Certain keys on keyboard cause unwanted actions. Please help.

Hi, I'm new here. Thanks for your great site!

I think the specs are close to accurate:
I'm running XP Pro, P4 approx 1.8 ghz processor, 256 mb Ram

Anyway, when I type certain letters in my word processor (or any other program) they work fine, but other letters do some crazy things. Example, pressing 'm' will close the current window.

I recently formatted my hard drive and reinstalled XP and it STILL does this.

I also verified I am using the correct keyboard under Regional Settings (English: United States).

Any suggestions? I am desperate. Thanks.

Welcome to Techspot!
You don't mention if the Kb is Branded eg; IntelliType , these often have specialized software where you can change the keys functions. Check in Control Panel.
BTW if that is a Portable , they definitely have Kb setup software.
Let us know.
