DeviceHostWindows.exe Crashing PC

[andrewj]

Help, please!

Several times a week my system is crashing overnight. Yesterday I ran a debug on the memory dump, and identified devicehostwindows.exe as the cause of the fault. I upgraded NPVR to 7.0.0.0 but didn't have the chance to reboot.

It crashed again last night. This is the last entry in the Windows Application log before the crash:

Faulting application name: DeviceHostWindows.exe, version: 1.0.0.0, time stamp: 0x6704dd00

I've also attached the NPVR logs from just before the crash.

Do we know what's causing this and how to fix it? Can we check that I'm using the latest devicehostwindows.exe?

Thanks

Next time post the zipped logs that NextPVR creates for you.

While the crash is not ideal it looks like your tuner is not locking a signal

2024-11-07 03:04:20.621 [DEBUG][4] locked=0, present=0, strength=28, quality=137 (took 32ms to check)

Does it work in WinTV?

Is it the same channel each time?

If you create a c:\temp directory, does it create a crash.mdmp file in it?

Hi
There was no crash.mdmp today, but there was from Tuesday, see attached.

[mvallevand]

Attachments need to be zipped and under 2MB

Still having problems with the attachment, although it's zipped and only 103kB. What am I doing wrong?

[andrewj]

Worked that time, sorry!

Was that crash.mdmp before or after you updated to v7?

When I load that crash dump, annoyingly it's showing dying somewhere in a Microsoft component (inside MSNP.ax), not DeviceHostWindows code, so I don't really have any visibility of what the problem is.

OK, I don't have a crashdump file from last night, after the upgrade, but I do have the Minidump file. Does this help?
