M4A87TD EVO
Gskill Ripjaws 1333
Ultra 550PSU

I get a green LED on the motherboard, but when I hit the power button I get nothing, know fans or anything. I checked for shortages under the motherboard. Verified everything is connected properly. First time builder im at a complete loss :( And yes the power button is connected to the mother board and the PSU is switched on =(

More about build wont power need asap
  1. I pulled the CPU out and noticed a bright spec of silver on an outside CPU pin.. Am I screwed? If it is thermal past and it got into the socket will i need a rpleacement CPU and mobo?..
  2. I dont see how it could have been thermal coumpund seeing as to how I didnt touch any until the CPU was in the socket
  3. Ive tried starting with he basics, no ram, one stick of ram, no video card. Ive reseated the CPU and heatsink. I get absolutely nothing no fans or anything. Any help would be greatly appreciated. This isnt my computer so im very stressed out as it is my first build and not my own.
  4. Verify that the 24 pin main power is secure, and make sure the 4 pin CPU power is connected.

    Here's a real good guide for troubleshooting.

  5. Both of these pins are secure and connected and I have done everything suggested in that thread
  6. Sounds like your PSU, motherboard, or CPU was DOA--can you swap the PSU or CPU with one from another computer for testing purposes?
  7. I can swap PSU's but not at this moment, I have a semi off topic question aswell. When I swap PSU's if I get nothing. Should I try to RMA the motherboard and CPU? Will newegg replace CPU's if there is no visible damage such as bent pins? As I stated above I noticed a sligt silverish area on one of the outside CPU pins this was before I installed the CPU and applied thermal grease so im starting to think its the CPU or Mobo.

    Also, if I cant use another PSU for testing purposes, will the paperclip thing work to test the PSU?
  8. If you've gone through all the steps, then it's time to try a different PSU.

    If you're within your RMA period, newegg will accept it with no hassle.
  9. Ok thank you all for the help.
  10. I cant get my hands on a compatible working PSU, should I try the paper clip jump start with the PSU connected to the case fans to see if I get anything?
  11. That'll tell you if it has enough power to run a case fan. :)
  12. Well I tried a different PSU, Absolutey nothing. I guess its time to RMA the Mobo? And in my third check of everything making sure everything was seated properly I somehow managed thumb contact on one of the CPU pins and there is a nice spec of what id assume is AS5.. Any suggestions on removing this? Also what are the chance of it being a bad CPU?
  13. If the spec that I saw on literally one of the CPU pins is the issue, would I atleast be getting fans or beeps?
  14. Solved...

    The power switch and Reset switch in my Antec 300 case were wired wrong.. The reset switch was labeled power and the power switch labeled as reset. It never crossed my mind to check this seeing as I have very little experience, but before I decided to RMA the motherboard I said what the hell let me try to short the pins with a screwdriver and then bam it powered up! Noob mistake I guess?

    Everything is recognized in the bios correctly and the CPU(Athlon ii X3) is at 33c. Is that a little too high for idle in bios?

    Now just to get the software installed and hope I dont get any BSOD's ><. Thanks to toms for the help!
  15. That temp is pretty good.

    Thanks for the update.
