HP PAvillion 8543C, max ram (256) Win98SE running Direcway satellite internet software. USB printer (LexZ55). While printing documents (10=60pages) occassionaly computer just dies. Like pulling the power cable, it just shutsdown. Only recent changes were addition of the sat internet progs(eats ram!) and doubling RAM. Never happened before those 2 changes so I suspect one or the other. Noticed other post saying "heat?" but comp will do this on start of printing, after 1-3pages, other times will print 50pages before shutdown. Time to upgrade comp??? Ideas appreciated. (shutting down the direcwayprog makes no diff-still shuts down sometimes) THANKS TonyH
