Need help with computer trouble shooting

Hey all,

I recently hit a snag with my computer, which is misbehaving (oddly) recently.

My entire computer is as follows:

i7-4790k
Z97x-UD5H (F10 BIOS, Gigabye)
X-850 (Seasonic PSU)
8GB*2 DDR3-1866 HyperX Fury
Xonar DG
PCE-AC68
PG278Q
BL3201PT
2 SSDs, 3 HDDs with various amounts of External harddrives.

Windows 10 Enterprise

I upgraded my GTX 970 (MSI Gaming 4G Golden Edition) to a GTX 1080 (MSI Gaming X 8G) back in October and it worked without a hitch, until two weeks ago it suddenly exhibited sudden shutdowns and restarts. I was unable to get an error log as Windows seem to not have an opportunity to make one. The sudden shutdown is similar to someone cutting the power to the computer and reconnecting.

I already have RMA'ed the GPU to MSI, but they didn't find any problems with it, they simply reapplied the thermal paste and checked the fans. The 1080 worked fine for another 24 hours after the RMA before starting the shutdowns again.

I also reinstalled the OS, and that didn't solve the issue.

Reverting back to my 970, things went back to normal (albeit with rather occasional sudden shutdown in maybe once a week).

I concluded, from the fact that 970 works and 1080 doesn't, that it isn't related to PSU, since it makes no sense to me that I can fully load a 970 without a shutdown, but as soon as I load 1080, it shuts down. Also 1080 should have been well within my PSU's capability,

It is also not the OS as I fully wiped the OS, reinstalled it and the problem persists. It probably also isn't RAM problem as that should have been seen on both 970 and 1080.

As a last resort, I went back even further and tried Windows 7, everything seems to be working fine now (nothing I did so far shut down the computer, even with 1080 fully loaded).

I am asking if anyone here recently have experienced something similar? Currently I am baffled, but I am kind of leaning towards the presence of a critical bug in Win 10, but doesn't explain why I was able to use 1080 for another 24 hours after RMA. Also no hardware related issues can answer why 970 works, Win 7 works, but 1080 with Win 10 doesn't.

Any help is greatly appreciated.

EDIT: Everything is at stock setting, no OC's.

I'll give it a shot later, I did try reverting back to an older driver before I RMA'ed my GPU (I believe as far back as 36x drivers), using DDU as well, but didn't work.

I haven't tried installing a fresh Win 10 system without using the 375.xx drivers though.

I am using Win 7 with 375 drivers too and it works fine so far.

I am currently at work, but I'll double check the BIOS, I am almost certain it's updated to the latest BIOS.

I'll check out the driver thing, I used another software called Driver Fusion Premium, though I am not too sure about how well it works.

EDIT: While I am here, is there a setting that I can use in Windows 10 that disables WU from automatically updating my GPU driver? When I reinstalled Win 10 the first time round, MS offered me 372 driver (which I think was the driver that I got from WU and used in my OS reinstall attempt), and I plan to go back even earlier than that (pre-WDDM 2.1 drivers if possible, though I doubt it with the AU).

Ok, I did a reinstall of Win 10 again last night, everything seem to be working:

1. My BIOS is indeed F10 already.
2. I installed 372.54 drivers, literally the oldest driver on the block for 1080 under Win 10. None of the older ones worked. I didn't try the 373 because 373 was one of the drivers I tested (after DDU of course) initially, and it still crashed on me.
3. I unplugged my Xonar DG in case its drivers or the hardware was causing any issues.

I will test things out further later on when I am off work. Thanks for the tip on the driver booster though.

Going to stress my GPU more later on to see if it will stay stable.
