Проблема возникает при неисправности выхода HDMI видеокарты (если HDMI-кабель и вход монитора исправны). © Axiom

Это обычное явление, звук издают дроссели подсистемы питания карты, тип звука и его сила варьируются в широких пределах, на это влияют: нагрузка на карту, БП, включение V-Sync.
Можно попытаться обратиться по поводу гарантийного случая, но следующий экземпляр может быть ещё хуже...

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.

SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name: KAMPC
OS version: Windows 7 , 6.1, build: 7600 (x64)
Hardware: ASRock, Z77 Pro3
CPU: GenuineIntel Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz
Logical processors: 4
Processor groups: 1
RAM: 8073 MB total


_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 330 MHz
Measured CPU speed: 1 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): 6626,731271
Average measured interrupt to process latency (µs): 4,783973

Highest measured interrupt to DPC latency (µs): 5819,024701
Average measured interrupt to DPC latency (µs): 1,835128

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

Driver with highest ISR routine execution time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation

Highest reported total ISR routine time (%): 0,102967
Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Total time spent in ISRs (%) 0,171664

ISR count (execution time <250 µs): 128019
ISR count (execution time 250-500 µs): 0
ISR count (execution time 500-999 µs): 0
ISR count (execution time 1000-1999 µs): 0
ISR count (execution time 2000-3999 µs): 0
ISR count (execution time >=4000 µs): 0


_________________________________________________________________________________________________________
REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

Driver with highest DPC routine execution time: tcpip.sys - Драйвер TCP/IP, Microsoft Corporation

Highest reported total DPC routine time (%): 0,216555

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 1542
Hard pagefault count of hardest hit process: 833
Highest hard pagefault resolution time (µs): 114733,153636
Total time spent in hard pagefaults (%): 0,978776
Number of processes hit: 12
