First off, just because it turns on doesnt mean it boots. lol. second, try cutting the wires as short as possible, set the switch to slim, jumpers 3 and 4 to on, and postbit to 0. it should boot. Also check the xilinx chip on the cr4, as I did an install one time, and accedentally bridged 2 of the pins on the cr4, and it would blink forever and not boot on any setting. I was able to fix it by removing the bridge, and it booted right up after that.
PS when asking for help with an install, pictures are extreemly helpful in the diagnostic process.
