Mouse Cursor Stopped Moving?

My mouse cursor stopped moving and I removed the stick because it seemed to be interfering with the USB.The next day, I was playing a game and the keys were malfunctioning and typing more than one letter each or the wrong letter altogether. I tried another keyboard and got similar, yet different errors. One keyboard types hn instead of n. The other won't type certain letters at all, like d or g. I couldn't even log into windows without using the cursor keypad to log in. The language settings are OK. I re-installed the drivers for keyboard and mouse. No dice. Sometimes the mistakes would change. H works now, but was zh a minute ago. I finally did a system repair and afterwards, I could log into windows again. I then typed every letter of the alphabet into Google and there were no problems, but 10 seconds later, the problem is back. Does this sound like a keyboard controller problem?I could type my password when running system repair, so the keyboard works in the boot area. Just not anywhere from windows log on or further.

Here's an example of the alphabet when typing without me correcting it.
