Intermittent PC Problem with BSOD/Latency

Hello thought i'd post this here with the hope of some expert help!


Bought new PC late last year, in the first few weeks i noticed minor/moderate audio problems (pops/cracks)... tried un/reinstalling audio drivers nothing really worked but issue seemed to go away on its own...


Today i turned her on... very laggy, not just audio pops but PC was generally very slow at loading and just generally really bad and nothing like it has happened before. Even the cursor was moving strangely, changing speed. LatencyMon readings were off the charts. Restarted a few times... BSOD happened once with DPC WATCHDOG VIOLATION after i tried to resize a window.


But after keeping the PC on for 15 minutes or so, the problem evaporated!


In my limited knowledge i think there is some deeper issue with a driver perhaps. But how it is able to resolve itself?!


The below LatencyMon readout is what im getting now that the problem has 'gone away' - it still says there may be an issue. As i said the readings were all the way red before. Noted drivers: dxgkrnl.sys, nvlddmkm.sys, rspLLL64.sys.


I ran the Driver Verifier and after restart it gave BSOD with DRIVER VERIFIER DETECTED VIOLATION and gave gdrv.sys.




PC (DESKTOP) - PURCHASED SEPT 2017
Windows 10 , 10.0, build: 16299 (x64) (FULL RETAIL)
Z270X-Ultra Gaming, Gigabyte Technology Co., Ltd., Z270X-Ultra
GenuineIntel Intel(R) Core i7-7700K CPU @ 4.20GHz
16338 MB total RAM
NVIDIA GeForce GTX 1080 Ti GIGABYTE GAMING OC 11GB GDDR5
WDC WDS250GB SSD
EVGA 750B PSU


I use onboard Audio (RealTek) and i am not running any other hardware. Windows fully up to date along with Nvidia display driver. Another strange thing is that sometimes my mouse does not work on bootup - i have to plug it out and in before it works.



Many thanks

CONCLUSION
_________________________________________________________________________________________________________
Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:07:59 (h:mm:ss) on all processors.

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 420 MHz
Measured CPU speed: 47 MHz (approx.)


Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.


WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.




_________________________________________________________________________________________________________
MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.


Highest measured interrupt to process latency (µs): 1474.8750
Average measured interrupt to process latency (µs): 80.896242

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

It seems that your DPC latency issue and the BSOD issue may be interlinked.

It seems that above driver was referencing an object using a user-mode handle. I would suggest updating the faulting driver from the motherboard support page or removing the associated program which appears to be Gigabyte Easy Saver.

The process which crashed seems to be the Gigabye App Centre.
 
EasyTune (and aorus?) is a year old. You can uninstall it to see if it's the culprit.

New bios available: F9b 2018/01/10.
RAM speed is currently 2666, but CPU and MB support up to 2400 (not overclocked).
There's a new version of Intel extreme tuning utility 6.4.1.19 (currently you've got 6.4.1.11).
The gvledservice.exe shows a lot of problems: could it be RGB Fusion? Or what?
In start menu, programs, there's an unknown folder: do you know what's that?
