Built new system, randomly freezing (hard hang)

New system built right before Christmas:
Intel i5 - 6600K
Asus Z170 Pro Gaming board
G.Skill Ripjaws V Series 16GB (2 x 8GB) DDR4-3000 Memory
EVGA GeForce GTX 970 4GB SSC ACX 2.0+ Video Card
Cooler Master Hyper 212 EVO CPU Cooler
Corsair CX750M Power Supply
1x SSD, 3x HDD, 1x DVD-RW
Windows 7 Professional

Issue:
After building the system, I installed Win7 and immediately updated to Win10. After getting the system setup, I started having seemingly random freezing and it's a hard hang. I have to turn the power off via the power button on the case. This happened while surfing the web (Chrome & Firefox), streaming video, playing Fallout4, and even while copying files. Generally 1-3 times per day. I can basically make it happen if I stream video (YT and other sites 😉 ).

Steps taken:
I downgraded back to Win7, thinking it might be a Win10 problem. Freezing persists.
I ran memtest86+ overnight and had no errors.
I'm not overclocking and the system runs in normal temps (max around 36 C which is normal for this CPU).
I was running a 600W power supply, which is on the low side for this set up, so I upgraded to a 750W, but the crashing continues.
Updated BIOS and all drivers. Win7 is completely updated.
Event Viewer gives: Event ID 41, Task (63) - Which is windows was improperly shutdown.

Really not sure what else I can do. Maybe wipe the drive and reinstall the OS?
 
What brand/revision of SSD are you running? Does it have the most recent firmware installed? Also, have you tried resetting the CMOS memory and then manually reloading your settings? Are you running the most recent available BIOS?
 
Look at the voltage your computer is giving your RAM. G.Skill is recommending 1.35 for those sticks, while other sticks are rated to run with as low as 1.2.

The SSD is a Samsung EVO 850 with the latest firmware. Motherboard BIOS is the latest revision. I am wired.

The following will be my check list:
SATA cables
Reset CMOS memory
Check RAM voltages
Possibly clean install Win10

I'm definitely open to more ideas. I appreciate the help! Thank you.
 
If you read the links posted, seems all involved are using Samsung SSD's (not necessarily a Skylake issue as some are touting). There are many more Skylake systems running without issue.

Interesting. I have a Samsung 840 that I've used forever without issue. Maybe I'll swap them and see how 840 works. If that solves the issue, maybe I'll try one of the Crucial SSD's.

Well, I tossed in my 840, updated the drivers for the previous OS installation and everything seems to be fine. Currently streaming two different video feeds in two different browsers. Hasn't crashed yet.

WTH? Is that a bad drive or just a weird thing with Samsung 850 Evo?

I don't know what that is, so probably not.

I did figure out how to up my Ram voltage from 1.2 to 1.35 in the BIOS (which is what the Ram is rated for) and, so far, no crashes. Man, I hope that was the issue.

I'm going to continue to test on the 840. If everything goes well, I'll switch back to the 850 and continue on.

I think this is the answer! Thanks Ketchup.

Upped the voltage to 1.35 and haven't crashed in over 24 hours.
 
So people saying it was a "skylake issue" were wrong. How about that, huh? 😀

For my Skylake build I went with plain Jane Crucial sticks with no heatspreaders. They're rated to run at 1.2 and the system has been rock solid stable.

Glad you got your system sorted.

Well, I'm glad he figured it out too, but Skylake DOES "have issues". Some new AVX bug was discovered recently:

Will never occur for 99 percent of users and already fixed via microcode with no performance hit. The kind of issue that happens fairly regularly with hardware and gets fixed without the public ever knowing. In this case, the public knew and tech bloggers need to get clicks. . . .you get the picture.
