I wasnt sure where to put this

:( Last night i left my computer on, when i went to bed at around 1, then this moring it was on the login screen so i guessed that it had updated or something, so i log in and it tells me that new hardware was installed or something and then just as its about done loading my homepage it restarts again, and then goes back on to my login screen so i press it, and it restarts again, and so on and so fourth, and i dont have any idea what to do.:(

Sounds like you may have had something go bad hardware wise, or you got infected with a virus.. Try to boot to safe mode and let us know if that works..

Alright, its just upstairs so i should be back in a few

[Marbles]

nah, i hit F8 and safe mode, and all it did was a list of things, like multi(0)disk something like that.

Any other Suggestions? anyone?

That's normal when booting up into safe mode. After it does that you should get a logon screen with the accounts. Click on Administrator and it will take you to safe mode. Once it gets into safe mode, do as ktkendall suggests.
