Need help tracking down hard-freeze cause

I have a mostly new-build comprised of:

New:
MSI Z170A SLI PLUS mobo
i5 6400 cpu
16BG crucial ddr4 (CT8081956 Ballistix Sport LT Red 16GB DDR4-2400 )
480GB SSD Plus (SanDisk)

Old:
XFX pro 750w PSU
Asus hd6850 gfx

I never had these freezes when I was on my previous win7, AMD phenom 2, ddr3 system, but now they regularly occur approx once every other day. They are freezes that require a hard power reset.

When I upgraded I bought a new ssd and installed win10. I'll be doing pretty mundane stuff (youtube in browser, rdp into work, etc.) and my system will lock up. No blue screen, nothing at all in event viewer. Sometimes the system wont wake from sleep.

I have a spare gfx card, but it's a hd3450 or something - no win10 drivers on the ati site. I don't have spare memory/cpu/psu.

I have run the windows' memory test and it showed nothing. I have just made a memtest86 bootable usb and will run that soon. I have switched the ddr4 slot and still get the freezes.

Since I had no problems with my old system, I'm doubting that the problem is psu or gfx. Indeed, I've checked the voltages with aida and they are fine. Therefore speculating that I have a driver/mobo/memory issue.

How should I tackle this?!
 
memtest showed no errors after 7hrs / 2+ iterations.

Going to remove ati drivers and see if default ones change anything. If not might have to try a new mobo or go through drivers. :-/ Perhaps I could make a linux boot. If the problem is stricly mobo then issue should still occur.
 
If it were me, I would try the following;

Try pulling a stick of ram out one at a time to rule them out

Try pulling GPU and run on onboard to rule that out.

Try disabling any power states / speed step / put windows in maximum power mode etc

Try fresh install of windows
 
Ah yes, I forgot I have CPU gfx.

I did put my comp 'full power' mode and was able to reproduce the freeze (again, with minimally taxing processes running)

My memory is a single stick and it's been thoroughly tested and switched dimm port as well - ruling it out.

My win install is fresh.
 
I've updated my bios. Leaving comp playing youtube stuff and disabled sleep etc. I've also 'removed' my gfx card driver. Windows has found something card-specific automatically though. I'm not sure if it's the same that I was using before. I've made a note of the version this time.
 
Yes, however the ssd is brand new. I have read that people have had temporary freeze/severe slow downs that ease up after ~20s. I've never read about an ssd causing hard freezes.
 
:rolleyes: Yes there is something in the event logs from after the freeze, when I boot the system up again, saying the previous shutdown was unexpected. This is hardly helpful.
