At A Complete Loss, PC Shutting Down and Rebooting During SLI WIN 10

[AceUnbound]

Good Morning!

Hopefully this is the right place to put this since I've never posted before.

I'm usually pretty good at troubleshooting using the internet and tech friends but this one has me stumped.

I have a 3 - 4 year old custom built PC with the following specs I can remember off the top of my head. Some of the original parts I had were replaced with some new stuff.

-Phantom Case
-ASrock Z87 Extreme6 Motherboard
-i7-4770 CPU
-650W gold 80 Power Supply
-2 x MSI gtx 970 Graphics cards
-1x 240GB SSD (new addition)
-1x 3TB Toshiba HDD
-1x 2TB Seagate SSHD
-1x 8GB DDR3 1600mhz ram

It ran like a dream during Windows 7 with no issues and even into recent months it ran fine. About 3 weeks ago though, after some windows 10 updates, any time I run the unit in SLI mode, it will definitely crash at least once during a game that uses it and then give me a memory leak dump file.

For reference, I had been playing Rise of the tomb raider optimized through geforce experience. It ran at 60fps most of the time for about 10 minutes then crash. It then restarts, I try to play again and it lasts a good 5 - 6 hours of gameplay afterwards. In Dota 2, I tried the same thing and it crashed twice on me, I disable SLI since I don't really need it for that game and it ran fine.


Things I have tried so far to fix this are:
-Change the size of memory allocation in the performance tab
-Reinstall all drivers with windows 10 ones if I found them
-Completely remove and reinstall Nvidia drivers
-Disable (or uninstall) Nvidia audio drivers
-Clean out the whole machine and every single contact thoroughly
-Install an SSD and perform a clean windows 10 install
-Uninstall Geforce experience / beta stream stuff
-Check the cards for overheating but they are relatively cool to the touch after a crash
-Switched SLI bridges to a new shinier one

One of my friends said it could be a power supply failing which makes sense but I wasn't entirely sure since the dump file directly cited the Nvlddmkm.sys which it shows doubled which leads me to believe it was a driver failing for both vs hardware.

Any advice would be awesome as to my next steps since, as I said, I'm usually good with this stuff but have no clue where to go next. Don't want to buy a power supply if there is a better option to fix it. Thanks in advance!

The only thing I was able to find which you haven't ruled out was this:

https://www.reddit.com/r/nvidia/comments/3htlbn/driver_troubles_w_windows_10_gtx_970/
The third comment mentioned flashing the vbios, and that it was the only thing that worked for him.
(be careful with that though)

They mention here as well that 650W is quite low for SLI 970.

So I'm worried that the power draw from the GPUs over the past couple of months has just been too much for the power supply.
PSU seems like most likely issue to me
Especially since you've reinstalled drivers and windows.

Yep, the PSU ended up being the issue. I ended up getting a 1000w instead just in case I have the urge to do a .... 3 way sli... in the future lol. We'll see though. thanks for your response!
