The problem is that it's running Microsoft software.

Install one of the Operating Systems that Microsoft created in co-operation
with a serious company, like IBM. That would therefore be: Windows NT,
Windows 2000 or Windows XP. Although with Windows XP, Microsoft decided to
tamper the one thing they hadn't really dared to lay their fingers on upto
then: the Windows kernel. Therefore, Windows XP might also be unstable. But
I don't know for sure. There's no reason to prefer Windows XP over Windows
2000 (unless you see your expensive computer as a toy), so I haven't
installed it yet. I am trying to stall that decision as long as possible,
until Microsoft devises some new trick to force me to update (i.e. a new
service pack that makes my computer respond twice as slow, or 'buy' a law
that forces people to only use their newest products).

P.S. It's so fun to bash Microsoft, especially because whatever you say
about them, there's allways at least half the truth in it :+).
