After a storm here in my city, the power went out at home and after it returned, my PC wouldn't turn on anymore and so i took it to the technician as usual for him to check and test for 3-4 days. Today I went to the technician to get my PC and bring it home. When I got at home, it wasn't turning on (NOTE: At the technician's establishment, the PC was working perfectly), so i went back to the technician at the same time and explained everything to him, the guy just plugged in the PC normally and the PC worked perfectly and said that it might be something at my home. Arriving home I tried to turn it on again, but the computer doesn't turn on, I tested it in different sockets, different power strips and in different rooms and it still doesn't turn on. Any tips?
NOTE: MY english is terrible , sorry
