ok sorry for double post but I just wanna say that I got everything to start working again and I dont think anything bad will happend again.... it was a bad power cable inside the computer that I had between the power supply and the harddrive so I fixed it and now it works again.... it was disconnecting something and then the harddrive disconnected so then the computer crashed... or freezed it self.... so then I had to restart it with the button on the front..... and then eventually my computer "removed" some windows files and then I had to reinstall the OS....
I hope it wont do that again couse then I´ll have to go to the local computer shop and ask for help.... and they suck.... and are expensive.... lol.... nah.... I just think I´ll call my friend.... he knows computers....
