Okay so I just started building my own pc. I have recieved every part except my CPU and GPU. Well today I decide to go ahead and put together the parts I already had and plug them into the power supply. After plugging everything in the way I thought was supposed to be plugged in, I proceeded to turn the pc on to see if bios would pull. I didnt know bikes required a CPU to run so nothing happened except my motherboard light turned on, my case fans turned on, and my power supply light turned on. I then realized that I need the CPU so I then proceeded to turn the power back off. I pressed the power button but it didn't turn off, something just clicked. I ended up having to unplug the power supply to turn it off. I am just wondering if something is wrong or if I messed up by started the pc without a CPU? I'm sorry I'm a major Noooooobbbb at this.
