Blasta, во время глюка сделайте отчет LatencyMon и скриншоты вкладки Drivers с сортировкой по ISR и DPC.

Перед использованием прочитайте документацию. Для завершения мониторинга нажать кнопку Stop. После зайти на все вкладки (Stats, Processes и Drivers) и посмотреть результаты. На вкладке Stats скопировать отчет целиком (в текстовом виде). На вкладке Processes задать сортировку по столбцу Pagefaults. На вкладке Drivers - по столбцам ISR и DPC.

[Blasta]

Готово. Этого достаточно, или необходима какая либо ещё доп. информация?

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 or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. 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  0:01:22  (h:mm:ss) on all processors.

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):   63331,518037
Average measured interrupt to process latency (µs):   39,534468

Highest measured interrupt to DPC latency (µs):       63328,520301
Average measured interrupt to DPC latency (µs):       36,331409


_________________________________________________________________________________________________________
MEASURED SMI, IPI AND CPU STALLS
_________________________________________________________________________________________________________
The SMI, IPI and CPU stalls value represents the highest measured interval that a CPU did not respond while having its maskable interrupts disabled.

Highest measured SMI or CPU stall (µs)                66,283289


_________________________________________________________________________________________________________
 REPORTED ISRs

 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:                 latmon.exe

Total number of hard pagefaults                       33
Hard pagefault count of hardest hit process:          17
Highest hard pagefault resolution time (µs):          22416,434288
Total time spent in hard pagefaults (%):              0,060017

Blasta, для эксперимента отключите IPv6 с помощью твика реестра

Код:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters]
"DisabledComponents"=dword:ffffffff

и перезагрузитесь.

[Blasta]

Отключено.

[Petya V4sechkin]

Blasta, наблюдается ли проблема в Безопасном режиме с загрузкой сетевых драйверов?

[Blasta]

Сейчас проверю, отпишу по результату.

Проблема судя по всему не наблюдается. Понятное дело, что переустановкой системы всё решается. Но не хотелось бы.

[Petya V4sechkin]

Проблема судя по всему не наблюдается

1. Для эксперимента удалите антивирус и сторонний файрвол.
2. Выполните инструкции
   Как определить, является проблема системной или вызвана сторонним приложением/службой
3. Какие сторонние клиенты/протоколы в свойствах сетевого подключения?
