you are probably overloading it by connecting all components of your computer with it.
Please post your computer config.

so you are not overloading it. Are there too many voltage fluctuations in your area? You do have proper Earthing?

no voltage problem , problem is in the board , i replaced the 4 relay but still problem exists , my guess the problem is in the battery meter (the component which shutdown the ups while the battery is low), cas if i short a capacitor the UPS is working fine , but the capasitor is in good condition cas i replaced it with new ,
