This is my build, all new parts except the 4870. I just put it all together last night, but it won't POST and when I power it on, I'm getting a lot of continuous, short beeps (power issues). I've swapped the PSU for a 650w that I was using before and got the same problem. I also swapped the video card for one that draws less power but got the same result. Any advice on what the problem could be? I am going to start by taking it all apart and putting it back together in case the mobo is grounded somewhere.

Thanks
 
What other PSU did you try?
Follow the instructions in the Basic Troubleshooting Guide sticky thread.
 
Antec EarthWatts EA650 650W Continuous Power ATX12V Ver.2.2 / EPS12V version 2.91 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC "compatible with Core i7/Core i5" Power Supply

This is the other PSU
 
I have done most of the steps on the troubleshooting guide, as far as reconnecting power/cables, but since I cannot get it to POST, I am not able to do alot of the testing that is suggested in the guide.
 
Are both the 24pin ATX power and the 8pin cpu power connectors hooked up?

I have made this mistake in the past is why I ask. Easy to overlook the 8pin.
 
Yes, I have checked both of those, at first the 24pin was not flush/plugged in all the way, but that turned out not to solve the problem.
 
Also, everything powers on, fans, leds, psu, etc. but it just won't post and i get the beeping
 
Did you clear your cmos?

Did you check your mobo manual for the beep codes?
 
I did check the manual and its a power issue. I have not cleared the cmos but i will do that before I take everything apart, hopefully that works.

Thanks for the advice
 
I found this on another forum. Might be helpful.

The main reason I'm making this review is becuse I had a problem with the board where I was recieving the quick beeping, "power error" prior to POST. Someone else reviewing this board also seemed to have this error and I think misdiagnosed the problem...

So, moments before I was going to RMA the thing as DOA I started Googleing a bit and I noticed that with Gigabyte boards this error can also mean a memory problem. Well, I tried swapping the memory all around and discovered I had the two sticks in the wrong two slots. (RT*M doh!) So, FYI: Correct placement is in the two slots farther from the CPU (the white slots).

Genius skittzle, I will move them around. It sounds like this guy was having the same problem as me. I took one stick out thinking it could be bad RAM, but it did not move it around or mess with it that much other than testing with just one 2GB stick.

Thanks again

Since you've followed the guide, please help me improve the guide. Which steps should I add and where?

The bench test would be my next step, I am going to test the RAM first as that seems to corrolate with the same issue that I am having, however your barebones bench test suggests the same thing. I think my problem was that I have my RAM in the wrong slots and I did not test enough, I only ran it with one stick to see if I got a bad stick of RAM.

Thanks
