I have the MSI P67a-GD53 B3 and it has an adapter that fits onto the motherboard in order for the header cables to be put into the mother board. The only problem is that when I press the On button on my case, I get no response. Luckily my board has a power button built in but it is quite irritating to have to unscrew the case every time I want to use my machine. This adapter fits into a "JCOM1" port, and I have checked the manual because I didn't even know where they went until I read it. Any solutions to this guys?
Ps, would just like to say how responsive and helpful this forum has been so far and is the main reason my first build has actually worked, so thank you very much.
