My Dell E-510 PC that I bought in 2006 had a major crash this morning.  I had run Windows 7 back up to external hard drive yesterday. This morning, it froze and would not reboot.  First, Windows prompted me to do system repair, then system restore.  Then I tried to restart normally - would not start. I reconnected the external drive, and got out the Windows Restore CD - not sure if it rebooted from the CD or from the hard drive, but it finally did complete the start up.  Running very slow.  I don't plan to replace it, but I think I need to get the files moved to the laptop.  I have the back up files, but not sure how I would access them if the PC completely fails.
