  1. Boot into Safe Mode.
  2. Use DDU to completely remove GPU drivers — most common cause.
  3. Clean-install latest GPU drivers from manufacturer.
  4. Run System File Checker: sfc /scannow.
  5. Run DISM: DISM /Online /Cleanup-Image /RestoreHealth.
  6. Check for .NET Framework corruption: use .NET Framework Repair Tool.
  7. If BSOD points to specific .sys file: that driver is the culprit. Remove/update it.
  8. Check RAM with MemTest86 — run at least 2 passes.

  1. Download Visual C++ Redistributable (all-in-one) from Microsoft: latest VC++ 2015-2022 Redistributable (both x64 and x86).
  2. Install the x86 version first, then the x64 version.
  3. Restart your computer.
  4. If DLL still missing: copy the .dll file from C:\Windows\System32 to the affected program folder.
  5. For games: verify game file integrity via the launcher (Steam/Epic) which will auto-install required VC++ runtimes.
  6. Never download individual .dll files from random websites — they often contain malware.
