So I just build a new rig -http://pcpartpicker.com/list/VRG7Ps
However major problems, firstly computer will not turn on. we press power button everything goes on for about 3 seconds but during that time red leds on the mobo flash on cpu, dram, and vga and the computer immiedietly powers off.We tried everything to figure out the problem but still havent found that out. But we did find something out. I think its the cmos pin thing when we put that on, the computer turns on and remains on but the mouse, monitor, video card doesn't turn on. Have 0 clue what to do.

FX CPUs support 1866MHz speed with one DIMM per channel.
Motherboard has Dual Channel Memory Architecture.

I read some of the reviews on Newegg. I couldn't tell you if you have a defective motherboard or if you made some mistake assembling it. I would exchange the memory.

Vengeance® Pro Series — 16GB (2 x 8GB) DDR3 DRAM 1866MHz C9 Memory Kit (CMY16GX3M2A1866C9R)
This memory also has an SPD Speed of 1333MHz.

AMD FX-9590 requires BIOS version 1903 or higher.

Motherboard Specifications:
4 x DIMM, Max. 32GB, DDR3 1866*/2133(O.C.)/1600/1333/1066 MHz ECC, Non-ECC, Un-buffered Memory
Dual Channel Memory Architecture

DDR3-2400MHz in your list is not a supported speed for AMD FX CPUs.

CMY16GX3M2A2400C11R
SPD Latency 9-9-9-24
SPD Speed 1333MHz
SPD Voltage 1.5V
Speed Rating PC3-19200 (2400MHz)
Tested Latency 11-13-13-31
Tested Speed 2400MHz
Tested Voltage 1.65V

SPD (Serial Presence Detect) is the a category of information that is stored in an EEPROM chip on a memory module and communicated to the BIOS when the computer is booted. The SPD tells the BIOS the modules data, such as its size, data width, manufacturer, speed, row and column addresses and voltage. With the information the BIOS can configure the memory controller to those settings.

1333MHz is too slow a speed for FX CPUs. Not to say an FX CPU won't run at 1333MHz.

FX CPUs support 1600MHz speed with two DIMMs per channel.
FX CPUs support 1866MHz speed with one DIMM per channel.
Higher frequencies require an overclocked system.

Uhm okay, so what do I have to replace and what are your recommendations ?
