Purely from a 'Hacker':

Some of the newer Computers will allow you to reset to an earlier date (when all devices and programs were operating)... This saves the bother of re-installing software.

Recently lost all sound from my PC - Investigation indicated 'No Sound Card'... apparently my blundering fingers inadvertently removed the operation...

Using the Windows XP Corrective Walk-through (blessedly simple process) I reset to a week earlier and 'All things became as they were'... a virtual Time Machine... and I didn't lose any files that were added during the period between the reset date and the present... most cool.

Good luck -
