Anyone know why my computer crashes while encoding with Tmpeg? The problem seems to be ram. I want to run about 1.5G of 266ddr but my XP doesn't seem to like it. All the ram is matching. If I run 512M everything works fine. I have even switched MB.

Asus MB
ATI AIW
windows xp
sound blaster audigy
lots of Hard drives
AMD 2000+
lots of money spent on a parishable item.
