Re: memory error in XP Pro

I'd guess your problem is the Dell.
I have no idea what BIOS settings Dell left available to the user; depending
on your BIOS settings/capabilities, you might try to disable Hyper
Threading, underclock the system, tweak memory speed (lower FSB, relaxed
latency - 3,3,4,8), reserve more/less RAM for the Graphics Card (don't ask
me why :), slightly increase RAM/video voltage.

Might also be that the mobo or the CPU overheats and the system slows down
causing AutoCAD to shut tdown.

Try making a new user account in XP and disable anything not needed (a basic
software/hardware profile - ex. disable USB ports, LAN, modem etc); see if
you can process the file.
