Hello charliejoe, and welcome to Seven Forums. I will try to help with this problem if I can. You have 5 dump files. Each one is very consistent.
Code:
BugCheck F4, {3, fffffa801f7aeb30, fffffa801f7aee10, fffff80002b94130}
----- ETW minidump data unavailable-----
Probably caused by : csrss.exe
Followup: MachineOwner
Code:
CRITICAL_OBJECT_TERMINATION (f4)
A process or thread crucial to system operation has unexpectedly exited or been
terminated.
Several processes and threads are necessary for the operation of the
system; when they are terminated (for any reason), the system can no
longer function.
Arguments:
Arg1: 0000000000000003, Process
Arg2: fffffa80200aab30, Terminating object
Arg3: fffffa80200aae10, Process image file name
Arg4: fffff80002b7d130, Explanatory message (ascii)
Each of them list as the cause
Code:

iaStor is a part of Intel Rapid Storage Technology which is Intel's Raid driver. It also contains Intel's AHCI driver. Several of the dumps included
Code:
EXCEPTION_CODE: (NTSTATUS) 0xc0000006 - The instruction at 0x%p referenced memory at 0x%p. The required data was not placed into memory because of an I/O error status of 0x%x.
FAILURE_ID_HASH_STRING: km:x64_0xf4_ioerr_image_csrss.exe
In my experience, an I/O error most of the time relates to the hard drive. It is possible that these are warnings of an impending Hard Drive Failure. It can also be the IRST causing the Hard drive to error.
In your system specs, you list raid 1 hard drive. If you are using IRST for the raid, uninstalling it will break your raid. I would suggest running tests to see if both hard drives are functioning properly. But, based on what I can tell, the problem stems from hard drive errors which copuld be the drive itself or some driver, such as IRST (Intel Rapid Storage Technology) causing it.
