I agree is the UPS or the PSU (the capacitors doesnt retain enought power to sustain the pc until ups enters in battery mode)
power the pc into the wall see if it has any errors in shutdown. some mb can hang during shutdown and some parts of the mb can still be on. if that the issue you have to pull power from the pc and clear the cmos. a lot of times this happens to asus mb.
 
Sounds like your UPS is the main problem. Its cutting off power to your PC when it changes mode. First guess is the battery in it is dead so when it switches modes to charge it it just cuts the power.

Are you using any kind of software control from your PC to the UPS so that it can monitor the UPS and change its power state?
