Repeated BSOD, caused by nvlddmkm.sys or dxgkrnl.sys

Welcome to 7F.

Your nVidia driver has indeed been flagged.

Code:

How many drivers have you tried and how far back? That will be handy to know before we proceed further.

The other (and probably the troublesome one, both are dated today) initially blames your USB hub.

Code:

Probably caused by : usbhub.sys

DRIVER_POWER_STATE_FAILURE (9f)
A driver has failed to complete a power IRP within a specific time.
Arguments:
Arg1: 0000000000000003, A device object has been blocking an Irp for too long a time
Arg2: fffffa800a51b060, Physical Device Object of the stack
Arg3: fffff80000b9c3d8, nt!TRIAGE_9F_POWER on Win7 and higher, otherwise the Functional Device Object of the stack
Arg4: fffffa8008dbb010, The blocked IRP

Taking a closer look at the blocked IRP though two things pop up.

The Intel Centrino Wireless (Bluetooth adaptor driver) and Intel Proset Bluetooth HighSpeed Filter driver.

It could be that both need updating.

You will need to visit the website of either the motherboard vendor or the chassis vendor for those drivers, if you can provide the info those vendors we can help you look for them.

Alternatively check the Intel Download Center.

Try the version linked below for your GPU. Follow NVIDIA Drivers - Avoid Problems for the cleanest possible install, test and report back.

I used the Intel driver update utility, and it told me there was an update for wireless networking, so I installed that.

Excellent, let us know how that goes.
