Actually i was referring to the unusual and totally unprecedented revival of my PC. I still don't know why everything happened and why it is working now.
The power situation is almost same in both places, while its true that in my working place(where the computer was located) i was facing some low voltage conditions recently. The technician guys asked if i used an UPS with the setup. Which i dont. I will buy a UPS soon.
I think those low voltage situations might have damaged my GPU(which is dead), but my PSU should support voltage in range of 110-230V, there is no switch in the back of PSU so i think i should already have a voltage stabilizer inside to automatically adjust such situations. But theoretically those should not have any relation with PC not booting up. Because in my home also the PC did not boot up. It did not boot up properly even when i brought it to the technician. But there is slight chance that those low voltages might be the issue.
I have been following pc hardware community(tomshardware, anandtech, hexus etc.) for eight years. I have seen very few people who actually uses UPS with powerful rigs. I mean do you guys use UPS?
