Problems already in the new build

I'm hardly an expert, but here's a take. Keep in mind that "won't turn on" is one of the most difficult problems to diagnose.

Is the heatsink properly installed on the cpu? Is the heatsink new out of the box and installed for the first time? If not, did you use thermal grease?

Second, are both the 24-pin and 8-pin power cables connected to the motherboard? Are any of the fans at least starting to spin?

I realize this is basic stuff, we just need to rule out the obvious suspects.

Also, you might try using only one stick of RAM in different slots.

That's off the top of my head. If everything is installed correctly, its either motherboard or CPU. If you have the other i7-860 system available, switch out its CPU with the new one. If it works, that will definitively rule it out as the culprit.

yeah all the power is hooked up etc....

I'll try the single stick of RAM approach haven't tried that yet, thanks!

Try to boot up using bare essentials. Single stick, VGA, mobo, CPU, PSU. If that has problems, test each individual part on another machine. A lot of issues with not powering up comes from a bad PSU, at least in my experience.

yeah I'm going to pretty much strip everything but the psu, heatsink and cpu, reset the cmos and see if anything happens. If not, I'm pretty sure it's a bad board, if so I'll be slowly putting in 2 dimms of ram and video card to see if I can get to the bios

PSU was working fine yesterday in my other rig, so I'm starting to believe I did something wrong or it's RMA time.

cpu not seated correctly or the front panel connections.

Did you check the your memory with the supported memory list? That got me once with an Asus MOBO with memory that should have been supported and just wasn't. New build did exactly the same thing yours is. Also, remove all your memory and see if you get an error beep (hopefully you have a mobo speaker). If you don't get some beeps, it is probably a bad MOBO. Just some quick ideas.

yeah it's constant beeping which shows a power error, BAH!

and the PSU powers up a dell xps 8000 fine...thinking it's the MB

Take the motherboard out. Check to see if there are any extra standoffs that your new board doesn't need - you could be shorting it out causing it not to start, or try and fail to prevent damage.

It's one of those "oh duh" things, but it's something to check before sending the board off.

I have seen some cases which have raised portions where the motherboard rests on, but they cause problems with some boards which don't always follow spec exactly, or the case doesn't.

Another way of diagnosing - run the motherboard outside of the case. Just set it on a non-conductive surface such as cardboard (not coated with anything) and bare minimum RAM, CPU and see if it runs. Don't put a video card in, and it should give you the error beep code for no video card installed.

I'm with numernorean, sounds like a standoff is touching the board where it shouldnt be

My RMA got approved, but I will definitely check out the standoffs and see before I RMA and let you guys know, thanks for all the help

This.

Tried everything, PSU is fine, the CPU fan isn't even getting enough juice to turn on when testing out the MB ouside the rig...thinking it's RMA time

Thanks again everyone for all your help
