I have had an issue where my PC's ram, motherboard, and fans turn on but the computer itself doesn't fully turn on. I thought It was a memory problem so I changed my motherboard and it worked but then it stopped working again. Then I thought it was because my graphics card was loose so I tightened it yesterday and it worked. This morning it didn't turn on again. I fixed it by unplugging all external devices including, mouse, headphones, and keyboard, and that somehow fixed it. Whenever this happens I hear some fans turn on, then when my computer fully boots the fans get louder which is how I know it's turning on. Someone, please help me find a permanent solution to this issue because some mornings it works and some it doesn't.
