GPU randomly restarts.

[Lordomus]

Hi. I recently reinstalled the OS because my PC was lagging so much. Since then in some more demanding games (ex. Witcher 3, Battlefield 4 on Ultra, sometimes The Division, once happened in Unigine Valley at some custom preset), my GPU tends to "restart" once in a while (sometimes after 10 minutes, sometimes it does not, sometimes after 8+ hours). It just shuts down the graphic driver, sometimes i get error saying "application access to graphics hardware has been blocked"( This particular error i have in Bulletstorm after 30-60 minutes of playing). Etc etc. It never happened on previous instance of Windows. Will there be anyone to help me?

PC SPECS:

• OS: Windows 10 Pro x64 v1607 (build 14393.693)
• CPU: I5-4690 (without K - locked frequency)
• GPU: EVGA GTX970 SC with ACX 2.0 - Drivers version: 378.66 - Also happened with 376.33 - NOT OVERCLOCKED
• RAM: Patriot Viper 3 2x4GB CL9 1600MHz
• MB: MSI H97 Gaming 3 - Bios version 1.11 (1.B)
• PSU: BeQuiet! Pure Power L8 CM 730W 80+ Bronze (PSU wattage was chosen towards future upgrades featuring in ex. second GPU )
• HDD: WD Caviar Blue 1TB
• Second HDD (I keep there less demanding games and stuff i need to work): WD My Pasport Elite 1TB

 

Software that is running in background is:

• Killer Ethernet Suite
• EVGA PrecisionXOC
• SoundBlaster Cinema 2
• Bitdefender Internet Security 2017
• nVidia Geforce Experience
• Realtek HD Audio Manager
• Steam
• Ocasionally Uplay, Origin, Bethesda Launcher or Epic Games Launcher (man why all of the companies wants their own steam?) 

 

Here is the list of what i tried to do:

• Turning it off and on again
• Force Windows Update
• Repair windows via SFC and DISM
• Reinstalling graphical drivers after uninstalling them with DDU
• Reinstalling the games
• Reseating the GPU
• Check voltages at 12V line (Voltages are normal - ranging from between 11.70V to 12.30V)
• Checking temps (all normal - GPU under load sitting at around 60-70C, CPU under load 68)

And by all means - No i haven't tried to swap the GPU's nor the PSU's. I'm not linus, i don't have a bucket of GPU's and a shelf of Power Supplies.

Do you have any kind of GPU overclock? Try reinstalling Graphics drivers using DDU.

As i said - Not overclocked and reinstalled.
