So i just bought my new HTPC from newegg, installed everything but when i power it up nothing is displayed on the screen.... now i don't know what to do... what is the problem ?? cpu ? motherboard ?? memory ??

Here's my stuff:

- AMD A6-3650 APU W/ AMD Radeon 65XX HD GFX Quad Core Processor Socket FM1 2.6GHZ 4MB 100W Retail Box

- G.SKILL Ripjaws X F3-12800CL9D-4GBXL 4GB 2X2GB DDR3-1600 CL9-9-9-24 Memory (it is listed in the motherboard's supporter memory list)

- Gigabyte A75M-D2H mATX AMD FM1 A75 2PCI-E16 1PCI-E1 1PCI DDR3 HDMI DVI SATA3 USB 3.0 Motherboard

- Crucial M4 SSD Micron C400 64GB 2.5IN Solid State Disk Flash Drive SATA3 6Gbps

inside Antec Fusion Remote case



So far here's what i tryed :

- Tryed two different 450W power supply
- Tryed with VGA output, DVI, and HDMI
- Tryed hooking a video card
- Tryed with an old computer screen, a LCD screen and even a plasma TV
- Tryed with only 1 memory bar, tryed different memory bar in different slot


The computer power up, CPU fan and PSU fan are spinning, but NOTHING is displayed on the screen. All black....

WHAT THE HELL !!


Now how can i know if the problem is the motherboard or the CPU ??? If the problem was the CPU, would it display something at the screen ?? At least some kind of error message ??
