Hello everyone. So for the past (almost) 2 years my PC won’t start at the first press of the start button. I turn on the computer, I hear the almost usuall sound that it makes but I can’t see anything on my screen and to be exact the PC won’t boot at all. I have then to manually turn it off by pressing the start button for ~7 seconds and then re-start it again. I have visited several shops that fix PCs and I got the same answer from everyone “Probably you’ll need to change everything one by one untill the problem fixes it self”. I have already changed my power supply cord and nothing still. So here I am seeking for help. Is it something that I can live with and just accept and if so will it make my PC burn out at somepoint? Is it minor or major?Thank you in advance guys!

you may need a new power cord or a new power brick
