Need system help FAST!

Ok I have tons of errors and other thing on my new pc and here is what happend: So I downloaded a beta game and it worked fine and I was playing online then suddenly the game freezed and I quited it by using task manager. So I looked at my internet connection and i saw that I pressed the off button on my network card so I decided to reconnect to my wireless network but it would just be stuckon “aquiring IP adress” and wont do anything after that. So I checked my routers settings and found nothing wrong so I switched the channel on the router to 11 from 6. So I went back to my new pc and it still cant connect so I decided I should reinstall the drivers for the network card. I reinstaled and it did not work. so i banged my hand on my keyboard when i was in the device manager and suddenly it said uninstaling driver! . II shut the uninstalation window down and I saw that my network card was missing from the device manager and so I installed it back…. It still could not connect so i (think I restarted dont remember how) and when I started my pc there was an error saying a file was mission in windows>system32>config>system. I went in panic and I closed my pc then opened it and the error was gone. When it started windows it was stuck on my desktop image and all i could do is move my mouse. I restarted a few times but windows would still be stuck on that and I cant even see mt desktop icons. I restarted the last time and I decided to go outside for 30min while leaving the system like that. I came back and I saw an error that said”cant find winsock” or something like that and my desktop opened and my system runned fine but I cant connect to my wireless network. I tryed to use system restore and I restored it because of the startup errors and slowness. When I tryed to open ntune I got like 10 errors that said nothing and my game was deleted. I scanned my computer and my kaspersky found nothing. my dell program suddenly stoped working because it said files missing. My kaspersky cant start because it said that it was half running and gives me an error when i try to enable to disabled compoments. So what i need to know is what to do to fix all that without losing any data. I will add more details soon.

Answer #1
1. Restart your computer. 2. Keep pressing the F8 key. 3. When the Windows Advanced Options menu appears, use the ARROW keys to select Last Known Good Configuration (your most recent settings that worked), and then press ENTER. 4. If you are running other operating systems on your computer, use the ARROW keys to select Microsoft Windows XP, and then press ENTER.
