Q: Mac keeps restarting after install

Ok my mac has been running really slow for about a year, I've tried all sorts but always getting the scrolling wheel, I'm on mountain lion and installed the original install disc leopard and clicked install, it's now turning itself off over and over again for the past hour  is this normal? I have nothing on there I want to keep it's all backed up, will it reboot soon, cheers

iMac (20-inch Early 2009), OS X Mountain Lion (10.8.5)

    You cannot reinstall Snow Leopard over ML unless you do a total reformat of the HD and start over again. I would strongly recommend against doing this and determine what you issue is first. You problem may be as simple as having an inadequate amount of RAM installed, how much RAM does the computer have?

    Try booting from the Install Disc by holding c key at bootup.

     

    You'll have to erase the drive.

     

    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.

    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)

    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*

    CCould this be the wrong Install Disc for this Mac?

     

    Hold alt key at bootup, what choices does it show?

     

    Oh, do you have Firmware Protection set?

     

    Firmware password protection in Mac OS X ...

     

    http://support.apple.com/kb/HT1352

     

    It would block usage of all the startup keys, like C, N, T, D, CMD+s, CMD+Option+p+r, CMD +v, Option boot will show a lock, and Shift, as well as booting from anything but the Hard Drive.

    So, it seems now you're booted from the Restore Partition on the Hard Drive, did the Leopard Install DVD show as a boot choice hold alt key at bootup?
