I kept getting a BSOD in OOBE when I was setting up Win 11 (error: SYSTEM_SERVICE_EXCEPTION).
I've seen people say that it's because of Windows 11 installing Intel display drivers, instead of AMD ones. It's also the same .sys file:
igdkmd64.sys every BSOD.
I deleted the .sys file, and now when it boots, it'll show the Win 11 icon, then it fades out after a minute or so, then the screen goes black for another minute or so and then it restarts.
I've gone into Safe Mode and opened Device Manager and now it shows the AMD Radeon driver installed but also shows the Intel display driver which I have deleted many times, which it might be using instead of the AMD one, but apart from that I don't why it's doing this when it's not in Safe Mode.
I booted out of Safe Mode, and it let me into the Desktop for 1 minute before BSODing with the same .sys file. It must have reinstalled itself after I deleted it. However, it has just let me back into the Desktop without BSODing but for how long- and it BSODed when in the Desktop.
Alright, in System Information > Display, it shows the IGDKMD64.SYS driver next to
Driver but also shows Intel(R) HD Graphics! So, was it AMD? Let's have a closer look. Under the first listing (Intel HD Graphics), the second listing (AMD Graphics) shows "Name" - "AMD Radeon HD 6700M Series"?! What's going on?!! I have no clue.
On the Intel listing it says Resolution: Not Available, but on the AMD one it says 2560 x 1440 (1 hertz), which means it is using the AMD one but then switches to the Intel one (when out of Safe Mode) which results in the crash.
I guess my theory below is correct! It shows the Driver for the AMD thing as "ATIKMPAG.SYS". But, even if I delete "IGDKMD64.sys" (for the Intel thing), "IGDKMD64.sys" comes back.
My theory is that it's switching between the AMD Driver and the Intel Driver, which then it crashes.
