not sure where to post this: Computer freezes when rending video

[Dewm]

So I built a new PC, (See specs)

Asus Maximus IV
i7 4790k (Not OC'd)
NVidia 780TI
2 intel SSD's
16GB G.Skill ram
corsair water cooling.



So here is what is going on. I built the PC about a month ago, it works PERFECTLY, I haven't had a blue screen a crash or anything with games or anything, my ram works and is identified by the comp etc....

The only problem I have is: When I'm rendering videos 70% of the time, my computer freezes HARD, like I can't move a mouse, I can't CTRL+ALT+Delete nothing. I have to hold the power button to restart the comp.

I don't get this with ANYTHING, BUT video rendering.

It does this on both Sony Vegas, and Adobe Premiere (The only two video programs I have)

What I've tried: I checked CPU and GPU temps with speedfan and they are at a steady 34C-40C. I updated my GPU drivers to the newest..

Any ideas?

Side note, I just did a windows memory test, and it seemed to run fine. And I am currently doing a "Silverbench" CPU stress test. Its been running my CPU at 90-95% for 5:00 minutes now. My CPU temp is 39C. And no lock up.

What is your power supply? maybe that's running out of power.

EVGA 850watt.

Everything in the system is brand new. I didn't reuse any of the parts (Just thought I'd mention it)

Maybe it's crashing due to accidentally shutting down the HDDs / SSDs to save power (under power option) Try setting the power to maximum performance and set the HDD power down to never. and see that solves the issue.

It was set to power off HDD's after 20 minutes. Although I don't know how that could be my problem, I've had it freeze as i'm rendering the video and surfing the web. :/
So I changed it to "never" but like I said,..I kinda doubt its the issue.

I updated my GPU drivers to the latest, and I checked ROG and ASUS for mobo/bios updates..and couldn't find anything.
