MORE computer problems...(Windows 8 stuck on Restarting Screen)

Well, here I am, posting from my laptop again. Ok, so as you probably know I had trouble with my old 2009 Compaq Presario CQ5210Y PC with Windows 7 (the hard disk went out, click here to read that post) so I got a HP Pavilion P-2330 with Windows 8 and 6 GB of memory for Christmas. (click here to read that post) It's been a good computer so far, it's really fast. BUT, I've had a few problems with programs not being compatible with it because of Windows 8. But my biggest problem so far is today I turned on the computer and sat down. The login screen appeared, and when I went to put my password in I accidentally hit a key on the keyboard (I don't know which one, but for some reason I think it was either the Windows key or the Control key.) Whatever key it was the computer went away from the login screen and said "Configuring Windows Updates, 0% complete, do not turn off your computer." So I waited. And Waited. And Waited. And Waited. And Waited. Finally I noticed in the bottom right hand corner it said "Your PC will restart in One day to finish installing important updates" so of course I assumed this meant it was going to boot up and tomorrow sometime it would ask to restart. WELL, finally it changed to 10% complete. Then 15%, which it stayed on for about an hour, then it finally jumped to 28% and eventually to 100% and then said Restarting. So I thought it would restart in about 20 seconds and I could use it. I was a bit off about the 20 seconds part, because that was at 4:30 and it's 6:23 now and it STILL says Restarting...So, my laptop which has Windows Vista is on the desk in front of the computer again..

PLEASE, if you think you can help me with this in any way, PLEASE DO NOT HESITATE to post a comment.
Update: December 28th, 2012 - 7:33 PM - It's finally back on, after 4 hours. I held down the power button until it went off then restarted it, lol.

Thanks,
