ok, I'll give that a try! Will it be sufficient to just remove the
Driver or should I remove the Sound Card and disable USB in BIOS? Also,
will Sound and USB be all? Should I also try another Graphics Card?

However, as the problem just occurs intermittent (sometimes it doesn't
show for 2 - 3 weeks, then again it happens 3 times a day) it may take a
bit for me to get back to this; I'll try to run some "heavy" tests at
latest over this weekend...

Cheers,
