I'm hoping someone can help me with a very stubborn problem: I'm running a machine that was built as a Duron 950, with an ECS K7SEM motherboard. The BIOS string at the bottom of the boot screen, for reference, is 02/07/03-SiS-730-6A6ISE19C-00. I've never had any problems with Win2k hanging (or any other problems, for that matter) with this machine.
Then, the other day, I replaced the Duron 950 CPU with a new Athlon XP 2400+. Now, Win2k (even after a HD reformat and clean re-install) hangs, seemingly at random. I've already tried switching out motherboards, and the problem remains. All tests that I've run on the system have come up clean. Is this a faulty CPU?
Thanks for your response -- Yes, I'm aware of the difference in FSB speed between the Duron and the Athlon XP, and the fact that being limited by the mobo's PC-133 memory will somewhat hogtie the CPU's abilities (I was attempting to increase the muscle of this machine under severe financial restraints, so I chose to upgrade the CPU but not the mobo), but could that difference in speed (between the FSB of the CPU and the speed of the memory) actually be causing the lockups??
