Blue screen DRIVER_IRQL_NOT_LESS_OR_EQUAL

HP Recommended
HP ZBook 17 G4 Mobile Workstation
Microsoft Windows 10 (64-bit)

I'm getting somtimes (now more often) a blue screen when opening a site frome school (Toledo and outlook). The error happens more often and is realy annoying. The error is caused by  ipeaklwf.sys and states DRIVER_IRQL_NOT_LESS_OR_EQUAL. What can I do about this?

I have also started getting this error with increasing frequency, twice in the last week. Exactly the same stop code (DRIVER_IRQL_NOT_LESS_OR_EQUAL) and file (ipeaklwf.sys).

 

I assume this is a problem with an HP driver. Please advise how to fix?

I've found a solution for my problem: I deleted 'hp velocity' and never got the error again. Hopefully it works for you too.

I'm consistently getting the Blue Screen of Death with error DRIVER_IRQL_NOT_LESS_OR_EQUAL with WebEx.  Sometimes this is when I'm starting a WebEx session, sometimes when I try to share my screen.

 

What Failed = ipeaklwf.sys

 

I'm using a new HPzBook 15u G4 Mobile Workstation with Windows 10 Pro.

Following the advice of another post, I uninstalled HP Velocity.  I then restarted, and ran WebEx again.  I was able to start WebEx and share my screen without a crash.  I'll need to try this again, but this may have solved the problem.

Uninstalling 'hp velocity' made the problem go away for me.  I've never tried reinstalling it.

I have had my Elitebook since late 2017 and I have used Zoom on it, but yesterday while teaching online using WebEx, I received the four screen four times with the error Driver_IRQL words and lpeaklwf.sys.  I see to turn off HP Velocity to solve this issue, but how do I go about that. When I search for it on my laptop, no results appear.  Please help!

HP Velocity has an icon(looks like a speedometer) in the sytem tray (near the time and date). By left-clicking on the icon, you can disable HP Velocity and this will survive reboots and you should no longer see any issues.

HP should be releasing a newer version of HP Velocity soon.
