Я испытываю случайную проблему с BSOD. Это означает, что компьютер запускается и работает, но в любой момент происходит сбой. Журналы говорят о силе ядра, которые мне не помогают. У меня есть файл дампа, который я не могу прочитать, но похоже, что файл cng.sys вызывает проблему, но я не уверен. Вы можете помочь? Спасибо дон

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 8e25f65c, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000000, bitfield :
bit 0 : value 0 = read operation, 1 = write operation
bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: 830e571f, address which referenced memory
