I cant get my Windows 7 to start up. I'm not sure if this is my PCs problem or windows. It starts up, gives me the ASUS screen where I can go into setup (though messing around in it hasn't helped yet). otherwise it goes to black screen where I can choose start windows normally or launch troubleshoot. if I pick start normally the windows logo comes up, loads, tursn black, and resets the PC. If I choose troubleshoot, it goes black for several minutes, shows the Windows 7 BG, and just gets stuck there. I'm not sure what to try to get it to boot.
