Youtube Audio/Video badly out of sync when system is under load.

Specs:
Gigabyte 1080ti Gaming OC
8700k @ 5GHz
32GB DDR4 3000MHz

If it means anything, this is only happening on my new system, my old system with worse specs, (i7 4790k @4.4GHz, 2x 970 SSC, and 24GB DDR3)

I don't know if this is a hardware issue, software issue, or overclocking/voltage issue. Please let me know what other information I can provide to solve this issue! The problem usually starts when I start gaming.
 
Random note.. What antivirus/firewall are you using? If you have Kaspersky or Zonealarm, I've had similar issues with them.

Network traffic loads up system/system interrupt usage in weird ways and that lowers actual network speed.
It is usually fine for hour to three hours after reboot and keeps escalating from there, at two to three weeks on (no sleep mode) speed would be at most like 3Mbit/sec and CPU usage at that time 80%

but still, likely not the issue but if you are using either one, try with windows default firewall, as far as I've noticed it or other software solutions have not had similar issues.

... Unfortunately and unwisely, no anti-virus

MERGED QUESTION
Question from grndy596 : "Audio out of sync during/after gaming."

There's a noticeable 1 second delay from the audio and video and it's making go crazy. It's been happening since I built the system and nobody has found a solution.

Asus z370-g mobo

i7 8700k @5GHz

Gigabyte 1080ti Gaming OC

32GB DDR4 3000MHz

NZXT Kraken X52 (240mm)

750W GQ PSU


Graphics and HD Audio drivers up to date. Audio has an occasional static/stutter as well.

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. 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  0:00:16  (h:mm:ss) on all processors.

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed:                                   3696 MHz

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):   2071.828562
Average measured interrupt to process latency (µs):   3.431079

Highest measured interrupt to DPC latency (µs):       2040.244120
Average measured interrupt to DPC latency (µs):       1.789729


_________________________________________________________________________________________________________
 REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

 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.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count:                 msmpeng.exe

Total number of hard pagefaults                       1
Hard pagefault count of hardest hit process:          1
Number of processes hit:                              1
