PC Shuts Down During Heavy Gaming

[dahfizz]

My pc keeps shutting down about 5 minutes under load (ie intensive games). I assumed it was my power supply, so I switched in an old one that I never had a problem with and the PC wouldn't even boot. I just disassembled the whole thing to see if there was anything behind the mobo that could cause a short and I didn't see anything. I am at a loss. Please help
My specs:
i7 4770k @ 4.5 th a
2x gtx 780 ti
1000w rosewill hive psu
Asus vii hero lga 1150 mobo
Samsung 750G sad
WD 1tb HDD
2x8 Gig Corsair vengeance RAM

theyre fine. Sometimes my hotter gpu will get up to 80 fine but crash when it is below 70.

have youm tried updating youur drivers?

try running prime95/furmark

I reduced the overclock on my cpu to x43 from x45 and i reset my GPU's to factory setting and everything seems to be stable. This is confusing to me, though. Wouldnt a bad OC give me BSOD? Or just crash the graphics drivers if it was my GPU's? I dont understand

Well as far as the crashes while ocing , i have just seen restarts an no bsods(i dont oc much)

PS- with that rig why an oc?

I mean I am a kid with a decent job and no expenses so i really dont plan on keeping any component more than a few years before an upgrade. Everything is cooled properly and EMT is obviously a factor (as we have seen here) but my gpu's are now stable at about a 15% OC
