I have this laptop that runs vista on it, and it just keeps rebooting.

it started doing this after i had done the following:

-I downloaded F-secure 2010 Internet Security from the actual website.

-Installed it.

-Allowed the program to reboot windows.

Now I did the exact same thing on a desktop PC that has Vista and I had no problems whatsoever. When the Laptop reboots it comes up to a windows screen telling be about completing system update 3 of 3, then after about a minute it reboots and continues to repeat this process never continuing to the desktop screen.


Can anyone give me some insight on how to fix this issue?

I am thinking it may be Power supply issues but I just want to know if there is anyway to get this fixed.
