My machine crashed at least 1 time every day, and that was with all memory caches turned off. Turned on, it crashed almost every 5 - 10 minutes. I replaced the bad memory and now its running fine. Your problem might be caused by something completely different, but I just thought I was mention my experience. Good luck. --- Tim Jensen http://plasma.engr.arizona.edu/~toast/ Q: How many surrealists does it take to screw in a lightbulb? A: Two.
