So, my computer randomly shut itself off while gaming last night. I booted back up and everything seemed to be fine. Turned the pc off for the evening, then came back to it this morning and it wont turn on. When I press the power button nothing happens except i get a noise from my speakers. Its like, a fast low thumping that gets louder the longer I hold the button. Help with where I should go from here. Every search i do produces answers reguarding the motherboard speaker and i'm not getting anything in regards to that.
