TLDR: PC is back in action
Long story: for some reason, when I decided to boot up my pc which has been dormant for a week or two, it would power up for a few seconds then auto shut down immediately before anything shows up on the screen. So I handed it over to the repair shop and told them exactly what was going on. The next day I visited them and they said nothing seems to be wrong and it powered up normally. So I brought it back home and indeed it powered up like normal… Computers are really strange… or is it because I shouldn’t turn off and unplug from the power outlet on the wall? if you’ve any knowledge or experience with pc please let me know your opinions!
