Hi All

I switched over to Mac just over a year ago when I got my first iMac. I never do anything heavy duty but recently I have got an annoying probem - it restarts with no reason.

When it restarts sometimes it ges to the desktop and others it just gets to the grey apple screen. I have tried a lot of things including:
  • Clearing cache
  • resetting PRAM
  • Verify disk and permissions
  • Unplugging external devices

but nothing has worked. In desperation I have tried an archive and install but it restarts before it has had time to finishThe vent is warm to the touch but i'm not sure if it's normal. I am wondering if it is just over heating but shouldn't that just shut down?

Thanks for any advice or poinetrs!

First - what is your back up scene? Do u have any back ups on Ext HD. The fans could well be running more than normal because the processor is doing unnecessary work - it could well be the result not the cause.

Hi thanks for the reply

I only backup onto CD as I use it for very little, just browsing mainly.

I got it to archive and install os hopefully that will fix it.
