Can't get system to POST

Size wise your PSU should be good enough but it really sounds like it could be it. Anyway follow the guide and see if you mist something http://www.tomshardware.com/forum/261145-31-perform-ste...

currently trying the 1 stick of ram at a time, and it's getting me past the POST screen, this is a good sign to me, as this could mean very few things: Bad RAM or bad DIMM slot...or maybe still the psu isn't strong enough

12 sticks of ram, it only takes one bad one.

Well, it would get me to past the POST screen and tell me that no boot device was connected. I knew that no device was connected as I had everything disconnected at the time. So, I powered it down once I saw it got past POST and hooked up the Solid State Drive (where I plan to install Win 7 Ult x64) and one of the DVD drives, and then I went into the BIOS to change the boot order, saved it, and now it won't go farther than the motherboard display screen...

One of those items is either faulty or the PSU is chocking on it, try a HDD and the DVD

I know this is resurrecting an old thread, but that's pretty much what I'm doing, resurrecting an old build too. I never got it working and even my so-called "techie" uncle couldn't get it working either (he didn't even work on it, he just bought a new computer instead.) Thing is, the build has been bugging me ever since I had to leave Alabama, but now I'm here again and would love to get it working by the time I leave, the 15th. I've tried numerous things, even some new school magic (I took a hardware class when I was in Florida at the local community college and it really taught me a lot) but here I am again, stuck at the boot up.

It has one dvd drive, the solid state drive, 1 stick of RAM per CPU, the SR-2 has two sets of 6 DIMM slots per CPU and I mean that I have 1 stick of RAM in each set. The 9800GX, both CPUs and 4 cpu fans (Noctua model cpu cooler, it has a push/pull airflow system).

Here's the problem, when installing Windows 7 it shuts down. It gets past the Windows loading files screen with the gray bar at the bottom, but when loading up the flag that windows 7 has when "starting windows" it shuts down. I did not happen to look at the error code display bit, but I'm quite sure it can duplicated.

This entire time I've been under the impression that a more powerful power supply is required, I think it's true. It's currently an 850w Ultra X4 (I <3 Ultra) but I got it assuming that it would be enough power to power all that stuff, and now that I think about it, it might not be, as it doesn't have two P8s and I'm having to use P6s instead...could it be that the SR-2 PSU would fix this issue and I could be done with this haunting build?

Ok, I've solved myself with a good amount of serious troubleshooting, I apparently don't know how to read the instructions when it comes to mounting brackets for the Noctua coolers, of course, it could just be that those are the most complex coolers I've ever had to use...this issue is solved...
