Hello. I have a Alfa Digital 1KVA UPS which i bought last month. This is a second time i'm having problem with it. The one I'm using right now is a replaced one because the first one had Loud Noise problem so i replaced it after a week. Today this UPS restarted my PC when i was'nt doing anything at all and it was on desktop. The voltages of my house were doing a little bit fluctuation at that time but it happens every now and then so it should'nt be the problem i guess because it was doing well in the past days with same power outage and fluctuations. Now I don't understand why it restarted my PC for no reason. There's no Virus no Spyware nothing at all in my Windows 100% sure. I want to know that is my UPS is again FAULTY because UPS are supposed to protect from high/low voltages (Fluctuations) power outage etc. or is it some other kind of problem. I bought it from Galaxy Computers but I'm not blaming them for it. So kindly HELP me out.
