Apple PC keeps restarting

I have a Apple Mac Computer Model A1225.
That keeps restarting before it comes to the login screen. I've put the hard drive into another Mac and the same thing happens, the computer starts in safe mode quite well though..

Any help will be greatly appreciated

Did you installed any software recently? Try to recall any recent installations or hardware upgrade to the Mac.

Before you reinstall - did you try to reset PRAM:

No problem, reinstall is what I would try next (see first post). Good luck!

The A1225 is a Core 2 Duo iMac. Do you have the original installer disc? Command r probably won't work for you.

Have you tried booting into single user mode to run fsck -fy?
Have you tried running disk repair and permission repair with Disk Utility when you boot into Safe Mode?
I would try those first before reinstalling.

If it starts in safe mode, then you have a driver issue. You could try checking the log file while in safe mode to see what errors pop up during startup. You might possibly discover what error is showing up.
