When I hit the switch it spools up and then switches the Monitor on. It then counts to 64K, beeps and dies.
It does not get to the bios entry screen and therefore there is nothing I can do with the keyboard to stop the process.
I think Charles has hit the nail on the head. It is weird though as the computer is used daily and left for a maximum of about 18 hours between uses.
I got it working this morning and it is still running so I'll play with it tonight.
The Hard Drive was replaced 18 months ago. It looks like it needs to be replaced if it is the problem. Would be well worth backing up as much data as possible now.
Is there any 'ghosting' freeware out there which would help me replicate the data onto a new drive?
