I have searched many forums and tried a lot of suggested solutions but nothing works. I am sure that installation disk is ok cause it worked before (I was able to install Windows7 on my other notebook - MSI). What happens is: I boot with installation CD, it says 'Windows is loading files...' Then it says Starting Windows (mouse laser works at that moment). Then I get the screen with window which has a title "Install Windows" with options to choose language, keyboard, etc. and asking me to click next. But, the problem is that at that moment mouse and keyboard don't work at all. Mouse's laser is turned off, and if I press CAPS LOCK on keyboard it doesn't turn the LED on. Do you have any suggestions? Thanks!
