Hi,
We have three dumps, two of the same bug check and one different.
We'll start with the latest, which is of the
DRIVER_VERIFIER_DETECTED_VIOLATION (c4) bug check.
This is the general bug check code for fatal errors found by Driver Verifier.
Very simple stack and dump....
Code:

FAILURE_BUCKET_ID: X64_0xc4_f6_VRF_nvlddmkm+9a879
The device driver in violation is nvlddmkm.sys which is the nVidia video driver.
Ensure you have the latest video card drivers. If you are already on the latest video card drivers, uninstall and install a version or a few versions behind the latest to ensure it's not a latest driver only issue. If you have already experimented with the latest video card driver and many previous versions, please give the beta driver for your card a try.
------------------------------------------------------------------------------------------
The other two dumps however are of the
WHEA_UNCORRECTABLE_ERROR (124) bugcheck.
A fatal hardware error has occurred. This fatal error displays data from the Windows Hardware Error Architecture (WHEA).
If we run an !errrec on the 2nd parameter of the bugcheck (address of the WER structure) we get the following:
Code:
===============================================================================
Section 2 : x86/x64 MCA

[COLOR=#ff0000][I][B]Error : Internal timer (Proc 0 Bank 5)[/B][/I][/COLOR]
Status : 0xfe00000000800400
Address : 0x00003880051db720
Misc. : 0x0000000000007fff
We have an internal CPU timer error in both dumps consistent with Processor 0 (primary CPU core) and Cache Bank 5.
If after you update the video card drivers you're still crashing:
There is only so much you can do with a bugcheck like this until it comes down to a faulty processor that will need to be replaced. Start from 1 and work downward:
1. Ensure your temperatures are within standard and nothing's overheating. You can use a program such as Speccy if you'd like to monitor temps -
Speccy - System Information - Free Download
2. Clear your CMOS (or load optimized BIOS defaults) to ensure there's no improper BIOS setting -
How To Clear CMOS (Reset BIOS)
3. Ensure your BIOS is up to date.
4. The
only software conflict that can usually cause *124 bugchecks are OS to BIOS utilities from manufacturer's like Asus' AI Suite. If you have something like this software-wise, remove it ASAP.
5. If all of the above fail, the only left to do is replace your processor as it is faulty.
