No i am not certain that it is rock stable at her place, (it probably is not) but I really do not have the time to spend anymore on that PC right now. It has on board Video it is a SOYO PVM motherboard.
I just hope it will run for a while, next thing I would try is restore to before SP2 install. Maybe it has something to do with that COorparate Version of XP. Maybe I should go and buy her a legimate WIN XP CD.
