I assembled a computer yesterday and am having stability issues. Whenever I attempt to run Prime 95 or use Adobe Premiere, the computer black screens and restarts. The case is well-ventilated and HWMonitor clearly indicates this is not a temperature issue (~30 C). I have run Memtestx86 to no avail. I am at a loss and have had a video editing project dropped in my lap within the last half-hour that is due tomorrow (today by now) - and I can't use Premiere.

Any help is tremendously appreciated.

CPU: i7 4790k
MB: Gigabyte Z97X-UD5H
GPU: Gigabyte GTX770 Windforce 400MB
Memory: G.Skill Ripjaw DD3-1600 PC3 12800 (16GB, but only 8GB are installed at present because I had deluded myself into thinking they were the issue.)

Getting the vcore, etc., as I can. Need more?

I haven't turned the settings to that, but perhaps they are defaulting there. When I set it to "20%", the core temperature stabilized much lower (~30 C) and the CPU is now maxing at ~1.2 V.
