I just ran some DOS based diagnostic/benchmark software I have, and there is definately something wrong with my hardware. Disk speeds are way too low there, and the CPU benchmarks are also way too low. It does pass all the diagnostics I could throw at it. I guess I'll have to open the machine up and start pulling things out and see what makes it better. Sigh... -- Mike Pritchard mpp@minn.net "Go that way. Really fast.
