My pc seems to crash at the drop of a hat. Usually when screen redraws are happening in small areas (eg progress bars), sometimes when a small sound gets stuck in a loop in media player, sometimes when NAV or speed-disk are running. The OCA console say s a device driver caused a problem but no idea which. Used to get a similar crash when a device called NEC smart vision was to blame. This was (Ithink) linked to a now abandoned TVcard. The problem stayed but the device is now unknown. Any ideas? PC is Athlon XP 2000 ATI radeon 700, NISYS sound -5.1, 768Mb RAM BTW I have disabled Fast writes which I recall was a problem with an old PC running an Nvidia card.
