UP square stability issues

Per Mejdal Rasmussen

My UP square is becoming more and more unstable. It often required to be power cycled.
It is from the "UP² Pentium Plus Innovator Package" and has been running VMware for more than 2 years.
Any suggestion to where to start debugging?

Last part, can you check if replacing the PSU you may solve the issue?
