|Yep. "took a dump" isn't described in any of the service manuals I've read. You didn't even tell us whether it's a laptop or desktop system, whether brand-name or custombuilt, and as the others have said, exactly what(if anything) happens when you try to start up.|
And why are there no backups of your pics & music etc? If indeed the system has crashed it may still possible to save the data as long as the hard drive isn't damaged. You could always remove it and connect to another machine ( there are wrinkles to that process) to retrieve your files.
