I tried turning on my computer today and it gets stuck at the "Starting Windows" logo. It just hangs there indefinitely (usually only takes a couple seconds) and doesn't load. I then tried startup repair, and that just takes me to a black screen. After that, I tried putting in my Windows 7 boot disc to do a clean install, told the BIOS to boot to CD/DVD drive. It tells me to press a key, I do. I get "Windows is loading files" and then it goes back to "Starting Windows" forever, yet again. This happened so suddenly, it was working fine just hours before this. Please help me!
