After updating to Windows 10 Anniversary, my PC got this issue: every programs including Start Menu, Taskbar, Windows Explorer, etc freeze after I log in. I couldn't even log off, turn on task manager using Ctrl+Alt+Del or Ctrl+Shift+ESC. I searched and tried many methods but non has worked unless I roll back to previous build. Then I decided to format the drive and try a clean install to fix the issue.
The clean installation ran smoothly, however after that it always shows the BSOD error with ks.sys message whenever I log in. I haven't install any software or driver yet, except the Nvidia display driver I installed in safe mode.
Felling hopeless now. Please help guys.
