its just that ur ups gets overloaded with the sudden suge from puttin the monitor on
therefore it restarts .. in the process rebooting ur computer
yes u can add sata and dvd rom
dvd rom is no problem
for sata make sure ur mobo supports sata or ull have to get a pci sata card
if u dun have sata for now i suggest u stick to PATA
power supply is the min anyone would recommend u
so yeah itll take the load well enuff
