Hi,

So I built my first PC and encountered some issues. The fans spin, CPU fan spin, graphics card fans spin, and things that I connect via a USB work except for a keyboard and mouse. My phone charges, a light on a USB blinked, and that's all I tested. Also, there is no input from the video card and don't get a signal on my monitor. I tried multiple HDMI wires ad both HDMI ports on my graphics card. After thirty seconds, it crashes (all lights turn off and fans stop spinning) and then it starts again after a second. Help!

I think my CPU might be bad? I unplugged the 8 pin CPU power cable and then the crashes stopped happening. Also, this obviously stopped the CPU fan and the graphics card fan from spinning. Could it be seated wrong?
