Since a few weeks ago once a few days the ups stops functioning for about two seconds and completely stops the power supply to the pc, shutting it down forcefully. When I tested to see what happens when the ups gets no power by unpluging it, it works fine, powering the pc, so the ups battery still works. I already got corrupt files and I am worried that my pc components will get damaged. Can you please tell me what could be wrong and what to do?
