I've installed Windows XP on a pc which had ME installed originally which I have removed. The machine is a Hewlett Packard Pavillion. with:- 668Mhz processor 320Mb RAM 20G HDD Although it's working it seems to hang occasionally and the graphics sometimes don't clear when you close a window. Is this PC not good enough for XP or is there something I can do to resolve these issues. I have tried upgrading the Ram with 2x 256MB cards but it won't boot up?? Cheers guys. Dave.
