This just started happening recently after using maya on the same system for 3 months without a problem. I could be doing the simplest thing, and maybe after about 20-30 min. of work my computer completely restarts. I found about 2 posts with the same issue on a few newsgroups, but I've yet to resolve my problem. I've tried reinstalling my video drivers but I really don't know what else to do..
My Computer:
AMD 1600 Xp
512 ddr ram
plenty of hd space
firegl2 (latest maya certified drivers)
layla24 sound card
generic ethernet card
Windows 2000 Professional - Service Pack 3
