My Duron does the same thing. At 850 it never does this, at 900 it will do it once a week, at 950 it will do it about 1 in 3 times. It is 100% stable once it gets into Windows though. I tracked it down to the genaric 250w PS. I am too cheap to replace it right now so I keep my system at 900Mhz.
The COMPUTER is your FRIEND!
Happiness is manditory.
