Проблема плавающая, возникает с непериодичным постоянством. Так бы и не узнал, что есть проблема, если бы не внешний модуль wi-fi (TP-Link TL-WN822N), который просто дохнет и оживает только после передергивания шнурка.

Перед системником стоит стабилизатор, так что скачки исключены. Внутри системника чисто, внутри бп тоже. Материнка, блок питания?
p.s. Только что обратил внимание, что проблема затрагивает и звуковую карту (pci), хотя на звуке это не отражается. Все-таки проблема железячная?
