Hey, did you connect the 4 or 8 pin power> and the 24 pin power? try to look over every connection, Check the power switch button on the power supply too. Could be mostly your power supply since its not runing on at all.

You can get the PSU to start without the motherboard by inserting a paperclip into the motherboard connection like this

Then you can isolate the problem. If the PSU and then fans turn on with this mod, then you know the power supply works. Just make sure you have the PSU switch in the off position before you do this :p

Check to see if your power button is properly connected to the motherboard.

:eek: iono if i want to do that plug it in* shocks myself lol i dont think is my power supply it seems to be working i tried it on my old motherboard and it works fine. and i plug the 4 pin and 24 pin already but the only thing i get is the green blinking light what does that mean?

also i just bought my new cpu x4 940 and heres my motherboard
http://www.asus.com/product.aspx?P_ID=KX5kXQSmyaQaXVEP
maybe its possible i did plug it in wrong but i doubt it im sure the power switch is in there and i had a lil trouble putting the heatsink over the cpu but it wasnt hard i figure it out without forcing it but would it be ok if i take out the heatsink? and check the cpu i probably put it in wrong but i doubt that also and if i do take it out will the pre-applied thermal paste go to waste? and another thing my video card i tried to put it in my case it doesnt go in all the way i have a mid tower ..and ummm is it possible if i worked outside the case if i put the motherboard in the motherboard bag it came with on wooden floors and connect everything on that? or does it need to be in a case?... hopefully my computer parts arent fried.

sorry tho if im a noob i shouldnt build this myself but let an expert do it but please bare with me any help would be fine thanks again guys.

If you're sure all the power connections are plugged in right, then it could just be a dead motherboard. Could you swap out parts with your other computer?

I know you covered this - but sometimes there's a certain way to put the 4-pin CPU power connector. When I built mine, some of the little tube things were shaped differently and I had to turn it around. That was the problem. Maybe that could be it???

Boot it with the minimum components:

- PSU
- Motherboard
- CPU + heatsink
- 1 stick of ram
- Video card (If there is no integrated graphics)

If it doesn't POST, take out the stick of ram, and try with another stick.

You can also test it without the video card - if there is a motherboard
speaker. It will beep if it POSTS - so you won't have to check visually
on the monitor if it did.

Have you plugged in all the LEDs to the motherboard? Here is a picture but motherboard models can vary:

When I built my first computer my biggest problem was with hooking up the LEDs to the motherboard. It is so easy to mix them up. Glad to hear you got your system working.

^^ yep probably the hardest thing i had to do too, luckily mine was right the first time. Also making sure you hook up everything is another biggie.
