Two of the pins on my CPU was bent, I bent them back into place and installed them on the motherboard. I hooked up the fan and plugged the power supply in the monitor, etc, etc. I turned on the pc and the lights turn on and all the fans started moving, but it was strange because when I had turned on the computer a the fan seemed to make more noise than normal(not sure if that effects anything). There was no signal coming to the monitor but the computer was on. I pressed the power button to turn it off but when I had did that nothing had happened. I'm not sure if that's because of the CPU or not.
