So before posting this i was on my computer like usual doing nothing out of the ordinary, i began hearing some electric buzzing noises coming from the back of the case(i assumed from the power supple cord), after a few moments my computer shuts down i thought the power just went out(happens often here), tried rebooting, almost got to login screen before computer shuts down again, tried about 2-3 times with each reboot shutting down faster than the one before, also heard some buzzing noises from the same place. after that tried moving my power cord a bit because i thought it was loose, when moving the cord i did also hear the same buzzing noise as the one before. so after that i turned my power socket for my pc back one now i began to hear more aggressive buzzing, didn't want to try booting my PC yet was afraid it might do some harm to it. so here i am, asking for someone who might be able to help me, or at least identify the problem.
