Okay so I was trying to update my video driver and mistakenly started installing the wrong driver. It was going and then the screen went black FOREVER. I had to restart. When I cam back the screen wouldn't fix, so I had to go and do a system restore eventually (took a lot of attempts because restore kept lagging).
Afterward I found out through here that I'm only supposed to go through Dell to install drivers, I went through Nvidia. I did that, but for some stupid reason I wanted to undo what I did because it seemed like it reset something. I restored again and then my comp would not start right. I was getting a black screen, I was getting a hanging start up at the Microsoft Corporation page, at the Welcome screen (even though it said please wait not welcome). I tried to do system restore but it said it needed to check disk first. When it would run it said there was an unexpected error. I tried to run from safe mode command prompt but it wouldn't like me run chkdsk /f even though it did find some issues and when I restarted I started hanging again. Finally I started up with enabled bootup and I'm back here. But the support center won't work and something seems to be wrong with my anti virus, like it's not fully installed.
Where to go from here? Can I run a repair while still in windows or something?
