Where Did My Computer Run Off To?

I have a windows XP Pro desktop that I use for all Randy Peterman Digital Research & Development media related work.  That computer has plenty of horsepower and more RAM than most people know will fit into their computers (I exagerate, it has 3 Gigabytes, it boots up pretty quick due to that).  However, today at lunch while trying to record a little ditty I launched the machine and it had all of its sound drivers gone and borked.  I did a Windows Update to make sure I hadn’t missed something there… still gone.  So now I need to figure out what needs to be re-installed, what needs to be un-installed, or what needs to be dropped off of a cliff after all of the re-usable parts are harvested out of it [like the RAM].  Few things chap my posterior like a Windows Computer acting goofy.  Every Operating System has problems, but this is really starting to get on my nerves.  OS X isn’t perfect, Linux isn’t perfect (no matter which flavor floats your boat), but this stuff with Windows is driving me bonkers.  What on earth should make that happen?  I can’t tell, but if I can find a good recording package on Linux I’m going to kiss the Cakewalk software goodbye and jump to the Penguin.
