VIDEO DXGKRNL FATAL ERROR since GPU driver update - unable to fix it

Hi,

I am using an Acer Aspire VN7-791 laptop and I think something broke after the latest Nvidia driver update. I've taken the laptop apart about a dozen times already and cleaned it and repaired the motherboard (screws were broken that held the gpu and cpu fan in place so heating was terrible and it made the machine terribly slow). After fixing that though, I kept getting this DXGKRNL error and blue screens, I did a bunch of trouble shooting and fixes and reinstalling a previous GPU driver seemed to have fixed the problem. No blue screens for about a month, until a few days ago a driver update was pushed again and without thinking I installed it..

Current problem: Laptop boots normally, with the onboard intel GPU chip and the Nvidia 860M GPU, but as soon as a program tries to use the Nvidia GPU I get a bluescreen with "video_dxgkrnl_fatal_error", one time there was also a "dpc_watchdog_violation" (not sure if this is relevant). When the laptop boots after the bluescreen the Nvidia GPU will not load and then of course the computer works just fine, but of course I would like to fix the issue and keep using the Nvidia GPU.

Some troubleshooting and fixes I've tried:

• Cleanly installing the previous driver or other versions of drivers, including reinstalling the newest one.
  
• Reinstalling the gpu drivers in safe boot mode
  
• completely removing gpu drivers and uninstalling the device through device manager (used DisplayDriverUninstaller to get rid off nvidia drivers)
  
• sfc scan (no bad results)
  
• DISM /Online /Cleanup-Image /CheckHealth (no corruptions found)
  
• turning off antivirus
  
• running a malware scan
  
• checking disk health with crystaldiskinfo
  
• running windows update (computer is up-to-date)
  

Please if anyone can help me out with this, I would really appreciate it, I'm at my wits end here and been tinkering for days.
