So I recently replaced my computer case and connected everything... But my 4-pin cpu connection. I pressed the power button and it turned on for a literal spilt second; fans turned on and hdd light. I did that 3-4 times and opened my case and realized I didn't connect the 4-pin connector. I plugged it in and my computer did not power on at all. Did I mess up my mobo, cpu? Please resond asap so I can buy a new mobo/cpu
