Q: BSOD: DRIVER_IRQL_NOT_LESS_OR_EQUAL I have been getting random BSOD (DRIVER_IRQL_NOT_LESS_OR_EQUAL - Source: nwifi.sys) in the last 3 days. They seem to only appear when playing videos on YouYube, but it might be a coincidence.
What has changed in the last 3 days?
Nothing on the laptop itself. I plugged in a new keyboard and mouse (both USB), and a USB hub (USB-C).
I also installed new drivers for the Intel Graphics and "Intel(R) Dynamic Platform and Thermal Framework Manager" as suggested by Dell Driver Updater, but this was an attempt to fix the BSOD, which already happened before updating these drivers.
What are the laptop info and specs?

This is the content of C:\Windows\Minidump: (all 3 are the most recent BSOD dumps and match with the date and time of the BSODs)

What have you tried?
I have checked with the Dell System Detect utility to see if all the drivers were up to date; 2 weren't and I updated them (as written above) but that didn't solve the issue.
I have cleaned the system Registry with the CCleaner utility, but that didn't solve the issue.
What can I do?
EDIT:
Upon suggestion, I updated the killer drivers.
All seemes fine of a while, then, after the laptop went to suspended state, I noticed the external mouse stopped working, while the touchpad worked.
After plugging and unplugging, I rebooted.
Laptop stuck to reboot for 6 min (usually takes 6 seconds) then BSOD: DRIVER_POWER_STATE_FAILURE.

A: Looking at the dmp with Windbg, shows that the Wifi driver bwcW10x64.sys could cause the crash.

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If kernel debugger is available get stack backtrace.
Arguments:
Arg1: 00000000decafc37, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, value 0 = read operation, 1 = write operation
Arg4: fffff80e930ddcec, address which referenced memory

So update the Broadcom Wifi driver or connect via LAN cable to the internet router.
The latest dump is shpws that the Audio driver (IntcDAud.sys) causes the issue:

so also look for a driver update of your Intel HD 530. The Intel audio driver is bundled to the GPU driver.
