Just built my pc and am wondering, could the reason why it stops spinning be that i only have a 450w corsair power supply? I have 16gb ram, gtx 1060, and a ryzen 5 1400. Do i not have enough power? Also, the pc wont connect to my monitor and says no signal (using vga to hdmi), could it be that the graphics card is not working because not enough power? Also the graphics card doesnt light up so im thinking it could be that?
