My hp pavillion tx2000.

Hello,
goodday all. I so much appreciate your concerns in this forum. Please i hav the same problem with my tx2000. I was using it one day when my friend restarted it to check if the recovary manager was working. As it was recovaring, he quickly press it off and it started working but as i wanted to shut it down, it started installing updates of which the system was up-to-date.
The next time i put it on,it was then showing much critical updates. So as i connected it to browse, the screen was wavering. I off it and on it,within a short time, it will start again so before long, it went blank finaly. Please i want your help. I bought it off a friend and quite sure it has exceeded warranty. Please anyone in the house?
