Boot your Mac from CD, DVD, external drive or USB Flash drive.
Thanks for the reply, neither of the suggestions worked. I did the press option route and got a blue screen with two buttons-; one with a three quarter circle with an arrow and the other one showing click right arrow. Clicking on either of these shows the mouse arrow reacting with the button (going dark grey) but NO other movement.
Then rather strangely clicking fast on the three quarter circle button brings up what looks like a terminal pane, several lines of type are on this page one saying "mac-boot" which then typed then comes back with invalid word.
After several tries of doing this it sudeenly changed windows and went to a grey screen with a postage size Finder logo which flashed from Finder logo to question mark and then back again, on this screen the mouse pointer is not available.
Any further ideas anyone or should just skip it!

Any bootable drive should show between those 2, 1st one is look again for boot devices, 2nd one is boot from selected device, so it seems to be having trouble finding even the Hard Drive.
Tough without the Install disc, but some things to try...
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).
Resolve startup issues and perform disk maintenance with Disk Utility and fsck...
