So about a week ago I bought a new cpu for my computer to replace a G3220...my motherboard is an ASUS H81M-K and I checked it if is it compatible with it and it is. After placing the new cpu in I start up the computer and there is nothing showing up on the screen...the cpu, the case and the graphics card's fans are on power but no image. I have a 500W power supply which should be enough...do you think that there is needed a bios update to make it work, and if it is could you specify which version should be the best
