Need Inspiration with GPU Problem

[Ledury]

Good morning LTT users,

 

so I had 2x EVGA GTX1080 FTW running in SLI and recently decided to switch to 2x EVGA GTX1080ti FTW3.

Yesterday the first 1080ti arrived, which has been used for only a few months, but without any problems, so I swapped the 1080's out and put the 1080ti in.

The Driver is the same, yes I am using GeForce Experience btw, and the new GPU worked instant properly... till i started the first Game....

I had not much time yesterday, so here is what i already did, and what im going to do next:

• I did reinstalled the driver, but i would like to keep geforce experience as I never had problems with it, and enjoyed the possibilities it gave me
• I do have EVGA XOC running cause im an longterm EVGA user, and the GPU clock, mem, voltage .. all like its supposed to be
• GTA V does not work in "normal Mode" but easily in "safe mode", cities skylines works as usual, 3D Mark doesnt even start... every other game does worked for like 3 sec. and the freezed and stopped working
• i did checked all nvidia settings, everything just right
• COD BlackOps II has an interesting phenomenon, it starts, works 3 seconds, freezes 3 seconds, works 3 second and so on
• and no i dont thinks its the PSU, its an 850 Watt 80Gold EVGA G2 PSU which had powered 2x 1080FTW with heavy overclock without anyproblems ever
• I tried both BIOS on the GPU
• turend on/off g-sync

What im going to do:

• I've planned putting the card inside an second pc with an clean windows install, see what happens
• downclocking the card
• reinstall all directx
• if it has to be, reinstalling windows
• i could go back to one 1080 without changing anything, see if it works
• completly uninstall all nvidia software as experience etc. with DDU and reinstall only the clean driver
• turn off the geforce experience ingame thing, also it never appeard on game start as it did with the 1080s
• i do have an potential old psu i could use (550W) but i would have to rebuild 2 whole builds to get that one thing out into the other one
• i could connect all 4x 8-Pin (6+2pin) VGA connectors from the psu to the adapters the 1080ti came with (each 2x6 pin to 1x8 pin)

Normally i would count myself as an very experienced user as I've build so many systems, fixed all problems I ever had

but this time I'm interested in you opinion and your help

 

If every solution fails and i dont get it working i will contact evga

 

thanks for reading, looking forward to your opinions

Try DDU first, it's probably the driver that's ruined.

As expected, it wasnt the driver, but somehow it still is...

I restarted Win10 in Safe Mode, uninstalled all Nvidia Driver etc. even uninstalled all OC and OS Tools like EVGA Precision X OC, reinstalled only the GPU Driver, nothing else, aaand it doenst work like its supposed to be, which means f.e. Black Ops II is running now, but as far as i go back into the menu it crashes... other games still doesnt even start

The g2 850 should not be a problem. I would just clean install windows if i were you. It can be done pretty fast and you save yourself some time.

Well i did that yesterday, on the same system, having the same problems. I'm going to visit a friend after work, who has exactly the same card, and we gonna swap cards to see if it works, if it doesnt, its an Hardware issue with the card itself
