MSI Z87-GD65, Freezing while gaming, then reboot loop/bsod/total failure.

Question

Hey fellow MSI'ers
Im hoping to find a solution for my problem i have been getting. I build a custom gaming rig a few months ago (specs below)
Sinds a couple of days iv been getting wierd problems, System runs fine, i can do everything watch movies do work stuff. But when i start gaming it will work great for about 15-30 minutes, then i hear a click/beep thru the sound system, and a total pc freeze, screen freezes nothing works.
So i hit the reboot, then the system decides to turn itself off and get into a reboot loop, turning on for few seconds then turning off again for a few back on for a few, etc etc.
Only way i can get it running is pull the power, make sure the Motherboard has no charge left, then wait a bit and replug the power. Most times it will boot up fine and story starts at part 1 again.
First off i thought it would be temperature, tho im running a almoost ull watercooled system, (Ramm + cpu + video) and i put up temp controlls on my seconds screen, and they never got above 35, on any of the components.
Now seeing my build it is extreemley hard to quickly test a diffirent component, been running memtest with no problems, But when i do graphx/cpu stresstest/benchmark i get the same issue.
As i stated before it has been running perfectly for few months.
I read that PSU might be a problem, compatability wise with Haswell, tho then it wouldnt have worked for so long and just now giving these strange problems.
What i tryéd so far:
-Reinstall windows
-Flash bios
-clear bios
-unplug as much as possible
-diffirent ramm
-Running with or without crossfire enabled.
All same problems, i hope somebody has a idea without having to pull apart my custom build.
Specs:
-Cooler Master HAF XB
-Intel Haswell 4770k
-MSI Z87-GD65
-2x Asus 7970 in Crossfire.
-Corsair Dominator GT 2x4gb
-Corsair ForceGT 128GB SSD
-Antec TruePower 1200
-2x 512gb Seagate MomentusXT

Hi again,

UPDATE: Been running bencharmks/stresstest from onboard graphix, both cards disconnected. (lots of towels to be sure) and runs without problems, tho reallo low fps but thats expected.
Going to see if i can run 1 card at a time, see if i can cause the problem to happen again.
So did you agtually try it?
Yep, bleeding is nice job and dooing it right on all steps is needed so yeah great, but if your CPU can handel the stress and you have tested the PSU then i cant see other way.
Tip: take the hard loop,pipe, bridge(betwean the blocks away and add two 90angle fittings with long tobe, so you can rest each card away the pc 1 at time that way you dont need to bleed the system bitwean.
(allso rest of the toops needs to be so long that it can be far away...)
And yes you need reg edit your SATA drivers like xmad sayd, if you like to change IDE to RAID.
P.s. nice build! Hope you get it working 
Edit: You dont need to insert that PSU in the case, just connect wires whrere they need to be, at the momen for testing.
Edit2: My current needs little service and update( add backplate, water change, delid cpu and moving GPU to bottom slot).
Edit3: Wait that one 120mm low Rad keeps your sytem 32c??? Damn you have great chips, cold house or software issue. need for delid main is the heat i dont like and i have hmm 10 times that space to get heat off :D
