My main desktop computer crashed last night and I haven't been able to get it back up and running.

It's older (almost 6 years) and runs Windows ME. I was originally able to get it running in safe mode, so I tried disabling all of the McCafee stuff that runs at startup, but that didn't work. Then I tried running a thorough ScanDisk scan in safe mode but it hung in the middle of doing that. I even got out my startup disk and tried restoring the registy to before the crash and running ScanDisk after booting with that, but it hung there too. And now it won't even boot into safe mode.
Does anyone have any suggestions? I obviously have another computer that I can use, but the one that crashed has all my e-mail, contacts, favorites and files (of which about 95% of the files but none of the rest is backed up) so I really want to get it running again.
