Hello, I recently just finished building my new computer and everything inside the case runs nice and smoothly. All of the fans run and there is a green light on the GPU. I just start it up and the monitor just black screens. No BIOS or OS shows up. Here are my specs:
CPU: AMD A8-6600k 3.9 GHZ
GPU: Asus Radeon HD 7850 2gb
Memory: 2x4 GB Corsair Vengeance (8GB in total)
Mobo: FM2-A75MA-E35

One problem that it may be is that my processor has a pin missing. I could not find a schematic for the processor so I was kinda just hoping it was a grounding pin. Please don't just assume right away this is the problem unless you know for sure.

Also, the OS is on the SSD if it helps.

If anyone could help me out or give me anything to try I would love to try it and appreciate anything.

Hi, is the S/N number on the box or actual cpu?
I have an SN number on the box but it says : SN# 9P90423E30410

Also, does this mean my I need to update the BIOS to get anything to show up on the screen?

Ok, the number is 1308 so August 2013. So what you are saying is that it doesn't need that pin? Or what? Do I have to download the BIOS from the website? If so, how cause I cannot get on that computer.
