Lots of BSOD, like MEMORY_MANAGEMENT and IRQL_NOT_LESS_OR_EQUAL

You are using a outdated copy of poweriso.
You should remove it, the virtual drive function it uses is not properly compatible with windows 7
I suggest magiciso as a replacement.

In addition you are getting memory corruption errors, this could very well mean that you do have failing memory.

The best check for that is to run memtest86 overnight and see if it finds any issue with your ram.
RAM - Test with Memtest86+

Code:

Probably caused by : memory_corruption ( nt!MiAgeWorkingSet+52b )

PAGE_FAULT_IN_NONPAGED_AREA (50)
Invalid system memory was referenced.  This cannot be protected by try-except,
it must be protected by a Probe.  Typically the address is just plain bad or it
is pointing at freed memory.
Arguments:
Arg1: fffffa8d45db681b, memory referenced.
Arg2: 0000000000000000, value 0 = read operation, 1 = write operation.
Arg3: fffff80002ab15d5, If non-zero, the instruction address which referenced the bad memory
    address.
Arg4: 0000000000000005, (reserved)
