Windows XP SP2, 3 gigs of ram, 2.21 Ghz AMD processor (acer aspire), All-In-Wonder 2006 PCI Express card, 256 megs video memory, ATI X1300 base
The last 2GB of ram is new, just installed. Nothing else is crashing like this, though.
NOT running Open GL (but the same thing happens when I DO run OpenGL.)
It crashes about 1/5 of the time when doing ram previews IMMEDIATELY on trying to do them, and it crashes about 1/5 of the way through my export. I mean, AE is pretty damned useless if I can't export. I could almost sorta kinda live without the ram previews, but not really even then.
I found the problem... Nero... See, I didn't even realize Nero launched when I launched my computer, and I thought I had deleted it, as it was just a trial and I never bought the full version... I uninstalled Nero and put after effects through its paces, no more problems.
