Okay I've had my Acer Aspire 5517 for 3 years and it just now failed me. Yesterday I was on YouTube listening to music from there and I left it up for about 15 minutes and when I came back it had stopped responding( the browser) and it had restarted itself. Then as it started to restart it had said " Windows 7 FAILED to start. This may be caused by a corrupted hardware or software....blah blah blah..." I tried various methods of what's been posted and the only one that I'm thinking will work is uninstalling and reinstalling Windows 7. So I pushed Alt+F10 at the booting process, everything got loading until the box for Acer eRecovery comes up. It says Please wait a moment... and I had let it process over night and went to school the next day and it STILL says the same thing!!! My laptop did NOT come with a CD so I can't do any methods with a CD. I don't know what to do!!! Please helpppp!!
