Nvidia driver causing MC lockup Win10

[Ulfhednar]

Taken me a while to figure this one out...  My clue was that NvFBCPlugin would hang any attempt to restart the pc!

I noticed that MC would :-

• hang on startup flag if a USB device was connected at boot;
• lockup if I connected a USB drive;
• sometimes not see a drive even if it was visible/usable in Win Explorer.

MC usually cannot be terminated by TM or ProcExp once it has entered not responding state.  If MC thread is apparently terminated (no longer shown in TM list) GUI or start-up flag remains on-screen. 
Attempting to restart the OS normally will hang the PC.
System needs to be fully powered-off to recover the OS.  Hitting Reset not enough even with USB devices unplugged & w10 fast boot disabled to recover a working OS.

NVDA 390.65-desktop-win10-64bit-international-whql  seems to be the cause.  Clean install back to 388.71 so far resolves these issues.

Whilst this issue is probably HW specific, I think its worth sharing the info...

I am using MC x64 7.7 b2404 on Win10 x64 b170317-1834 on
Asus B350M-A
Ryzen 1800x
TEAMGROUP-UD4-3200


Mathias - would a MC.dmp made by TM help you?

Maybe..

I've been experimenting with nvda drivers & haven't yet found a 100% fix.
I still have usb device issues with the newest builds.
I have tried hooking VS to MC & tracking the crash - it doesn't seem to give much info.  Mostly the OS file version numbers are listed & nothing definite is revealed (like an exception or sth).
I used WinDBG on the mc.dmp & got only this -

Is it worth uploading the <300mb?  What else is contained in the dmp?  (e.g. could the dmp compromise data on my machine if it was taken by a malicious user?)

Sorry. did not see that I did not answer this

Hmm Useful maybe.. We can try

Pack it and upload it to http://multicommander.com/upload/

I just received some new mobo drivers from ASUS.
They seem to have resolved the USB issue.  I am having to go through the nvda drivers one by one to see if the latest builds still cause problems.
This may have saved you!
