Windows 7: BSOD during Skype call

BSOD during Skype call

I came home after my computer had been asleep all day (10+ hours), got on a Skype video call with someone, and within a couple minutes I got a blue screen.

The system seemed sluggish when restarting and windows was being a little finicky once it came back on - explorer disappeared for a few minutes and when it came back I noticed the Nvidia GeForce Experience icon that usually sits in my tray has disappeared.

I updated my GPU drivers yesterday as well as GeForce Experience. Nothing significant otherwise has happened in the last few days.

Welcome to the forum.

BSOD was caused by Logitech Camera driver. Please update it to the latest version available and see if that solves the problem.

Driver Reference Table - lvrs64.sys

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e)
This is a very common bugcheck.  Usually the exception address pinpoints
the driver/function that caused the problem.  Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003.  This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG.  This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG.  This will let us see why this breakpoint is
happening.
Arguments:
Arg1: ffffffffc0000005, The exception code that was not handled
Arg2: fffff88005a02fc6, The address that the exception occurred at
Arg3: fffff88005154758, Exception Record Address
Arg4: fffff88005153fb0, Context Record Address

Thanks for letting me know. I had a suspicion it was my webcam. Every BSOD I've had in the last three years was due to this same driver issue. The problem is they've never updated their drivers. I have downloaded what they have about 8 times and reinstalled it... and I usually go about 8 months before it craps out and I get another BSOD. Time for a new webcam I think :/
