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.
