Im building my first computer and i attached the motherboard power cable and cpu cable, and it powered on and gave me A6 code. I was trying to power it down and my dad hit the clear cmos button and it came off. I pressed the power button right after and it powered back up. I attached the video card and plugged it into the power supply and when i tried to power on nothing happened. I replugged everything and took out the video card and it still won't power on. I don't know if the clr cmos buttton did something or if the board just died. Please help!
