Certainly pre NT and Pre BSD (OS X) both OS's (Mac and Windows) where as flacky as hell. Software BSOD (and the mac equivalent) disappeared with the Dos/Windows (Win ME) line (and OS 9). These days a BSOD or a Kernal Panic is likely to be either a driver or more frequently a hardware problem rather than a problem with the underlying OS.
Just to ignore all the OS vs OS war of words thats being going on.... (why type it, no ones mind will change)
I reinstalled XP, I couldn't get the burning to work, there was no graphics card drivers for the 3 cards I have lying about and the on board card and my board didn't have the virtualisation settings required to run the new version of virtualpc which did look interesting. Oh and I got a huge panic when I thought I had messed Sims up :)
