For some weird reason, some of my keyboard keys of my deskop are acting very strangely. I don't remember a certain time when it started and I can't recognize any pattern as to when it happens and when it doesn't. The problem occurs in Windows XP, XP Safe Mode, Vista, and Vista Safe mode (I have a dual boot system) Here's what's happening: When I push the I, K, comma, or 8 keys (notice how they are all in the same column), instead of just getting that character, I get extra characters afterwards. For example, I'll push the k key and it will print "ksfda", pushing "I" gives me "IWREQ", comma gives me ", xvcz", pushing 8 gives me "82431". There are a couple things that I have noticed:

1. It does not happen every time I push the key

2. It happens in all OS and applications I have tested

3. The characters coming after the desired ones are in the same pattern (column order: 2, 4, 3, 1 from the left of the keyboard in the same row as the key pressed.

4. Pressing "]" will sometimes give me "]t", and if done in Notepad, will bring up the "Find" dialog window

5. I cannot seem to remember a specific time the problem started, although I have been defragging, using TuneUp Utilities + CCleaner, and installing lots of new programs lately.
