Having a strange experience with my stationary old 939 it has been running 24/7 for years, all of the sudden it did not want to take input from keyboard and mouse (both ps/2) at log in screen or at boot cannot get into BIOS and still can't but now I am typing from USB keyboard and using USB mouse and all seems fine 
so I will have some time to figure out replacement, an i5 should be enough and I need no fancy graphics.

Any excuse for an upgrade

It is funny how oddly behaved hardware can sometimes turn, especially when its been running 24/7 and shouldn't really be as susceptible to the problems caused by repeated cold/warm off/on cycles.

I wonder if it had been working with windows as OS
