mmmm, strange, i think it is a hardware conflict somewere, because he has the same with playing music and deleting some videofragments in a standard boot.
is this possible? if is there a way to figure out which one causes the conflict? and were do i report this then?
in the meantime seems the problems almost solved here, just copied al the important files to second partition, so that would normally be kept if we reinstal winxp?
Thanks for the help nyk and johntramp!
