If you search on google for AMD's recommended hardware list, double check you're power supply is listed for your cpu. I had the unfortunate experience of having a power supply explode and catch on fire, because I read the model number wrong and thought it was OK for a new 1.4GHz Athlon. The symptoms: system unstable/freezing under no load. Under load, the power supply exploded. hehe -Keith On 28-Dec-2001, Greg Lehey wrote: > I've been using AMD processors almost exclusively in my main work > machines for over 4 years, and I've been very happy with them.
