I am able to type this by having set my key repeat rate options to the lowest possible. Please tell me whether there is some plist file which may have become corrupted somehow that I can delete, or what else I might try!!

I have also tried removing the two enter keys to make sure that there is nothing wrong with them, and they appear to be fine.

If there is a delay in the problem occuring (i.e., it does not happen immediately when the computer is started, but waits until I am logged in), it sometimes happens straight away once I have logged in, but sometimes it occurs only after a few keys have been pressed (not necessarily including the enter key).

Here is another hint as to what may be occuring / has cause the problem. This morning, I awoke the computer from sleep, and it had 0% battery but did not seem to know it. It ran for a minute or two, then the screen flickered a little and went off, but the computer was still running (I could still seen images on the screen, as if I had only turned the brightness to 0). When I then turned on the computer with it plugged in (having to restart it by holding down the power button, as it would not wake up again), I had this problem. I suspect the power monitoring system did not do its job, as the computer should to have awoken from sleep, and then some files must not have been put away / closed properly, including some system file related to getting input from the keyboard. That is why I suspect it to be corrupted in some way.

I need to be able to use this computer for my university work! Please, I am in need of help as soon as possible!
