Fix: BSOD Error atikmdag.sys on Windows 10

The Blue Screen of Death is a nightmare for Windows users, and no one wants to encounter it. Microsoft has been trying its best to rectify errors by providing regular updates, but there are still many issues causing Windows to crash.

Many people have reported a Windows 10 BSOD error caused by atikmdag.sys while upgrading from Windows 7 or Windows 8 to the latest build, i.e., Windows 10.

This blue screen of death doesn’t allow the PC to boot normally. Restarting the PC also doesn’t work in this case, and this error persists.
