Hi there I have a fairly new iMac running on Mountain Lion and it is stuck on the grey screen with the apple symbol and a spinning disk.

Several times it has restarted with a bar at the bottom that gradually turns dark grey but then switches off again on completion.

Can anybody offer any advice.



iMac, OS X Mountain Lion (10.8.1)
