Recently, my iMac has started to stutter when I'm doing anything, e.g playing a movie file, it starts stuttering, and then the video will stop while the audio continues...

In Logic, it won't play a song, starts OK, then starts stuttering, then comes to a stop.....

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.

iMac 24", 2.4 GHz Intel Core 2 Duo, 4GB 667 DDR2 Ram, 1TB HD.

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.

OK, thanks for that.

I couldn't see any dirt etc. on any contacts, but I've replaced the power cable with another. I'll do some work, see how it runs, and post back.

If that does not help, open Disk Utility in Utilities and check the Hard Drives SMART Status at the bottom? Does it say Passed or Failed? I have seen some of your symptoms when the hard drive is starting to die.
