I have a P8P67 with a i5 3570k and 12 gigs of Crucial DDR 3 Ram (1x8gb 1x4gb, two slots don't work.) I recently switched the case from a cooler master HAF 912 to a Cooler Maste HAF XB EVO. Since then I have had this issue:

If I turn off the computer, it does not boot up. My TV which is connected to the PC via PNY Geforce GTX 460, changes from blank screen to saying no signal, meaning the TV is receiving something from the computer but its not receiving a signal.

When I hold the memok button, the PC shuts down then starts up, and I get the PC to boot no problem. This works every time without fail, however I have to do it every single time the PC is in any shutdown state, including sleep mode.

I have reset the CMOS with the jumper and same result.

Any suggestions?
 
Solution
Ok so I finally and randomly figured out the problem. There was a 4 port USB 2.0 PCI card on the board. I disconnected it. That appears to have solved the problem. Don't know why that would cause this.

When I hold the button the computer boots and it says memory ok every time, then to press f1 to access bios.

I had 2 x 4gb of Ram before and needed more ram to use virtualbox. It cost too much to purchase 2x 8gb of Ram and I didn't think the performance hit would be too big a factor going from dual channel to single channel so I bought 1 8gb stick and use it with 1 of the 4gb sticks.

Anytime I use either of the two slots closest to the processor, the computer will not boot and the mem light is solid red. If I use either other or both other slots it boots in the manner I describe. I will test both sticks individually and see what happens.
