Could use assistance interpreting a crash dump

Question

I have an issue where my computer seems to crash when going into sleep mode, and also randomly reboot whilst already in sleep mode.

Consequently I've had to stop using sleep mode whilst I try to understand what's wrong.

I installed Windows Debugging Tool and tried to interpret the .dmp files, and messed around with some symbols, but no luck.

This only seems to have started happening recently, I'd say within the last 2 weeks.

Could anyone help me interpret these crash dumps? http://we.tl/T0QOCjwl6t I would be eternally grateful

Is there a step-by-step guide anywhere to debugging this, or does it really require a lot of pre-requisite knowledge?

An Intel exmployee in answers.microsoft.com posted on 9th October 2015 regarding the ICCWDT.sys issue:

You may be hitting a known issue in the Intel ICC clocking driver. We are trying to drive resolution to this internally

There is a fixed ICC clocking Windows driver. This driver is expected to be integrated into the next release of Intel XTU.

This issue was caused by installing the Intel Extreme Tuning Utility

Answer 1

the crash seams to be caused by the driver ICCWDT.sys (Intel watchdog driver):

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
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 kernel debugger is available get stack backtrace.
Arguments:
Arg1: fffff8009f3f7838, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000008, value 0 = read operation, 1 = write operation
Arg4: fffff8009f3f7838, address which referenced memory

Look if Intel offers a newer driver.

The confusing part is the paged Instruction pointer. Also run memtest86+ to detect memory issues.
