Upgraded my Mobo and Graphics card, now system doesn't work.

Before i fully assembled my computer (to the case), I did a pre-test with the whole system, It turned on just fine but I only could have turned it off using the PSU switch (clue?), not the power button, when I fully assembled it, the light from the mother board was the only thing working. What could have happened?

-ASUS P5G41T-M LX PLUS - LGA 775 - G41
-Cooler Master RR-910-HTX3-G1 130-Watt 92mm Hyper TX3 CPU Cooler
- 4gb DDR3
-Cooler Master Elite 460W ATX
-ASUS EAH6670/DIS/1GD5 Radeon HD 6670 GDDR5 1 GB
- 3ghz Core 2 Duo CPU

  1. I'm guessing your CPU cooler is installed incorrectly. I had that same problem when I upgraded my system and I reinstalled the cooler exactly how the instructions had it and it works perfectly fine now.
  2. It's my third time tying that out, and still having the same issues.
  3. my advice is take out the video card and RAM and try booting, then put the ram and boot if it bootsm turn it off and try the video card
  4. Many things .....

    You used the MoBo standoffs ?

    8 pin EPS cable plugged in ?

    CPU fan plugged into CPU header ?
  5. Nope. Could this be caused from a small shock?
