we asked for more info, not some details
do you know how many pavilions exist?
please provide exact model number, it must be written near the screen or over/under the keyboard, if not there it should be under the laptop near the serial number of the laptop
the laptop can't have 2 512 kb ram modules, it must be 512 mb modules, so it must have 1 gb of ram, shared with the video card so if it has a intel card you should have around 950 mbs for linux
if it has another video card, the ram used by video card should be different but still should have enough ram for kde or gnome
about the remastered version you mention, no idea what it is or why it gives you problems, i never had a successful remastered version but honestly haven't tried it in many months
don't see the reason to start now, pclinux updates so many things so fast, i don't find it useful anymore
