ok, here is what happened. my samsung laptop had USER32.dll problems on every other file after i installed the new graphics driver. After i searched what to do, i decided to restore my laptop to factory default. I have a samsung laptop, so i pressed f4 while the computer was turning on, but it showed invalid restore area or something like that. While i was searching, what is that, the laptop went black and wont turn on anymore. So, what was all of that, what is the problem and how can i fix it?
