well, t sounds as though the UPS is not receiving power. Check that it's cable is properly plugged into the wall. Also verify that it's internal ground fault interrupter has not tripped, it's usually a little red button on the back of the unit, it should be pressed in and should stay that way, if it pops out then there is a problem with the ground of your electrical outlet. Also check that the breaker for that electrical has not tripped at your fuse box.
Since the UPS is not receiving power the batteries have discharged and that is why your computer cannot start, there is not enough juice from the UPS to boot it. There is a chance that the batteries in your UPS have gone bad or that something has become faulty in your UPS. Try plugging your computer and monitor directly to the wall bypassing the UPS to see if they work fine.
