I have installed Win7 x64 several days ago and it worked very fine, but jesterday i did not "shutdown" my pc, but tried to send it to "sleep" instead. Damn! It is totally broken-down! When i first tried to start after this, i choose the "start normal" option", all i got was a black screen, so i rebooted and choose the "repair from dvd" (or similair) option, it doesnt do much more: first it says "Windows is loading files" and when the progressbar is full it switches to "Windows is starting" with the Logo, but still black/white, and thats all, once i waited over an hour but when i came back: the same picture. (i dont know exactly if the "sleep" was the reason, but it seems to be the most likely answer to me) Is there a way to fix this??? If not, i would have no problems with reinstall (no important data, and all programms were installed to another partition anyway) but even that seems impossible to me, as, if i insert the boot-dvd and restart, the repair tool starts automatically and i have no option to choose a complete reinstallation.
