Как узнать, нужно ли менять блок питания? Иногда мой ПК не запускается, появляется черный экран, и мне нужно снова включить его. Иногда PIC зависает и его нужно перезапустить.
Я провел диагностику блока питания и ниже представлен отчет:

Current Timer Resolution (100ns units) 10000
Maximum Timer Period (100ns units) 156001
Platform Timer Resolution:Outstanding Timer Request
A program or service has requested a timer resolution smaller than the platform maximum timer resolution.

Platform Power Management Capabilities:Supported Sleep States
Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.
S1 Sleep Supported false
S2 Sleep Supported false
S3 Sleep Supported true
S4 Sleep Supported true

решение1
Вам необходимо провести стресс-тестирование вашего источника питания.
Сначала вам нужен способ контролировать напряжения, обеспечиваемые блоком питания. Чаще всего вы можете найти утилиту, предоставляемую производителем материнских плат. Раньше я использовал speedfan.
Так что вы ищете? Отклонения больше, чем + или - 5%. На 12-вольтовой шине это 11,4 В до 12,6 В или 4,75 В до 5,25 В на 5-вольтовой шине. Тот же принцип применим и к 3,3 В.
Весьма вероятно, что ваш компьютер практически мгновенно зависнет, если параметры блока питания существенно отличаются от номинальных.
Теперь, когда ваш монитор работает, начните сфурмарк. Это нагрузит ваш графический процессор. Если он работает >10 минут и напряжение не падает ниже 5%, это хорошо.
Теперь вам нужно запустить что-то вроде Prime95 одновременно, чтобы нагрузить и центральный процессор, и графический процессор.
Если напряжение падает ниже 5% от номинального, вы, вероятно, нашли свою проблему.
