That sounds very much like hardware.  Does the fan seem to be running
more than it used to?  If so open the back up and give it a good clean
out with a vacuum cleaner.
If that does not seem to help (or even if it does) try booting into
the ram test and leave it going for a few hours to see if it shows any
problems.

As to the mouse, if it is battery driven then try a new battery,
though hopefully you have tried that already.  Otherwise try a
different mouse.

Do you see anything in syslog when it starts going wrong?
