In general use, the cursor will not move smoothly, when I move my mouse, it jumps across the screen, missing out all the space between....

When I reboot, it's ok for a few minutes,then starts, and gets gradually worse until I need to reboot again.

It started a few weeks ago, but is gradually getting worse, to the stage where I can't do much on my mac.

Also, I've repaired disk permissions, to no avail.

Any advice appreciated please.
Hi, it seems a strange one. I would firstly power down and remove the power lead and check it for nicks and creases and make sure that it is seated correctly when you reboot. If you can...swap it out for one that you have borrowed from someone.
