I'm back, and with another handful of weird possible stability/crash problems, Need help!

So after a year of trouble shooting my issue with amateur PC enthusiasts lets call them, I had already half given up. I was just playing the waiting game for either upgrades, or a miracle somehow.

After trouble shooting the entire build i found that the main issue i was having was due to the 2nd gtx 590 in sli mode being in the 2nd pcie slot of the mobo not the recommend 3rd slot. Either way it would have 1 or 2 expansion slots, so they had room to breathe. Overheating didn't sound like an issue. I then tested the 1st 590 in another build to see what i was told is calle fragmentation. IT looked like bad pistols that wer 10 fold the normal size of one. But hese werent static, upon a reboot or waiting long enough the "fragmentation would move.

Got the GPU back and still the same main issue, the way I knew the issue still persisted, was that i could recreate a glitch where upon rebooting i would be forced into the startup repair utility which would fail every time it tried. I would have to recover from a manual back up to get back where i was and 1/10 times that wouldnt work and I was force to do a clean install.

I had someone walk me thought more trouble shooting, and even though the second GPU did not show fragmentation on the other build, it did on the 1st slot of this initial buid. So i sent in the 2nd gpu and mother board. I got a replaced gpu back, and the mobo was most likely a refurb i didnt check.

(sorry for bad grammar im in a lot of pain and running on fumes at this point.)

Anyways thats 1 gpu refurb, 2 gpu replacements, and a mobo refurb if not a mobo replacement.

Now here is where your probablly gonna decide to leave this thread, or just have a crazy reaction like i did to the fact that this build still did not work. By not working i mean BSOD happening more than it ever should, just like it did when i was working on the GPUs.
By now both my computer wiz friends and the tech guy that was helping me are MIA and i just deal for some time. Eventually a random friend recommends memtest. Now i thought i understood memtest but apprently id wanna test each stick individually in another build which i had no clue my backup PC could do.

So now as it turns out 1 or 2 of my g skill sticks had a problem... at this point im so fed up i cant take it, and my memory gets a lil foggy as to why i choose to get the same mobo again out of pocket for a fresh start, as well as swearing off g skill and opting for my beloved corsair.

Everything worked great memtest passed beautifully, ages went by with no problems. I was very very very happy. Until.... BF4 is released. The successor to the title i based my entire build around, that i never got to enjoy using on that title. (i leaned a lot thank god, but one thing is for sure, im staying away from quad sli.) I couldnt manage Diablo 3 on min settings without crazy load on my quad 590 setup. So i opted for a.... again... yeah not the best choice but the top of the line nvidea at the time, a super clocked 780 ti. Do keep in mind at this point have not even begun to think about over clocking when i cant grasp the concept of stability with my components lol.

And now for the awaited not so TLDR TLDR.... i memtested again, this time its the corsairs i went with, vengeance 1866hz quad sli ddr3s. One odd error with 9 sucessful passes after.

Now ram is my weakest department in computer building or understanding, keep in mind i tought myself everything i know, so you can imagine why my luck has been so bad. My first error was a test 7 no pass , not sure if thes if the info is relevant but here it is...
Falling Address: 00647d08d28 - 28029.5mb
Good: ffffbfff Bad: ffffffff Err-Bits: 00004000 Count: 1 CPU 0

Now this was a nightmare for me but ive been told even if you get an error in memtest it doesnt mean the ram is bad. So i remove sticks in slots a1 and c1 leaving b1 an d1 as recommended by the manual. 3-5 full passes (i was asleep) no errors. So i drop it down to just b1 as recommended for for card, eventually find that no matter which stick i have in slot a1 while the other 3 are in b1 c1 and d1 the error will pop up.

Now i can tell you what ive seen, but i cant tell you what 75% of means or waht that means i should try. Ive basically hit a brick wall here and thats why im here right now.

Sorry they may have been a tiny swap in the funky slot in that last troubleshooting. The issue error pops up when i have 3 cards in b1 c1 and d1 while a1 is the last one in my quad channel setup that sets off the error. But i have tried to duplicate it with success using just slots a1 b1 and c1 instead. But as i dont know all that much about ram im afraid to try any other ram combos or just the one stick in the faulty slot.

Sending in the mobo or any part really is almost not worth it to me because of the level of work effort and pain required to do so thanks to my injury. This current mobo is a 2nd one i purchased just like the whole new set of ram because i couldnt deal with another RMA.

Now i would just go along with my business happily with 24 gigs of ram atm in my mobo but the other day i had 1 or 2 freezes and 3 BSoDs in under 6 or 7 hours of just what most would call light multitasking but anyone who doesnt sit at a computer all day would think is too much multitasking to be able to mentally process.

So im begging for advice here, and if my only result is to RMA the mobo, can someone recommend another mobo for my build? All my ram is fine, idk how to test he cpu other than stress testing it and its fine, and now with the 780s those are now the only component i havent tried running not in this build. The only thing i can think of that i didnt mention is that i cant not play battlefield with thesettings as they are since i was deprived of it when i initially started this insanely long project. The game already has a crazy tenedancy to crash, kick and DC plyers, and even crash their own servers so idk if i should worry about the fact that my 1 780ti was uneder 99% load the entire time i played that game. Im hoping to give the sli dual 780s a shot tonight but i dont wanna attempt that till ive finished masking sure the cord managment and everything else is just perfect.

Again thank you so much for your patience.

So my built at this very moment is.

EDIT:I did forget one important thing which is why ive been driven to write all this, windows in general is being so buggy and i cant take another full install and getting everything adjusted to where i usually have it its insane. The windows issue is just a lot of the freezing up thanks to windows explorer loading pages or software... damn its kidna dumb i went to include this edit and im so burnt out i cant even think of just one of the 3 other things that were really just pissing me off like BF4 just completely crashing (but i believe thats just battlefield for now not related to my issues)


CPU: Intel Core i7-3960X (3.30GHz)
RAM: 24Gb of 32Gb Corsair Vengeance dual/quad channel DDR3 (CMZ32GX3M4A2133C10
SSD: Samsung 840 pro 520+ sequental read 500+ write (500Gb model) i also have 3 purely storage WD caviar blacks i believe (3tb 64mb cache 7.2krpm)
GPU: 2X EVGA GTX 780 TI super clocked GPUs w/ ACX air coolers
Mobo: Asus Rampage IV EXtreme (non BF3 edit nor the black version)
PSU: Corsair AX1200i wired into a Corsair H100i Cpu Cooler which shares a mobo usb splitter with the Cosair Link Commander unit for the full Link setup. Usually Software is uninstalled and everything but the PSU cooler is unplugged to prevent any conflicts with stuff like msi after burner or even asus AI suit which i hear can be just as bad as running precision X which hasnt given me any conflict issue that i can tell...
