[2004, 20h2] A way to find the process causing IRQL_NOT_LESS_OR_EQUAL BSOD's?

[Garacesh]

A couple of our machines are throwing this error reasonably frequently since updating to 20H2 over the summer, and I'm struggling to track down why.

I've used NirSoft's BlueScreenView to analyse the memory dump but the 'Caused By Driver', 'Caused By Address', and 'Crash Address' fields are all blank.

 

 

Is there any reliable way to chase down what's causing the problem?

 

Edit: @Katy and @tgpips have pointed me towards WinDBG which has satisfied my need. Leaving thread/link here for future searchers!
