BSOD approx every 8 days overnight when PC idle but on

Hi everyone

I have been experiencing a reasonably regular BSOD (I think it's always of the "irql_not_less_or_equal" variety) and have finally getting around to doing something about it.

I have attached the DM Log collector information.

Any assistance would be appreciated; it is usually occurring when the PC is on but not in use overnight, but on an odd occasion when not under heavy load and appears fairly random to me.

It is my work PC, Win 7 Pro x64 and doesn't appear to occur on any of the other work PCs which are identical except for a couple which are almost identical in all specs.

Thanks

sorry, with attachment this time

Well I just experienced another BSOD while working this time (using Revit 2015, with Chrome, Outlook 2003 and windows explorer all running).

Anyone able to shed some light on this please?

Hi All

This morning I had a few programs open (Chrome, Revit 2015 and Outlook 2003), and I experienced another BSOD (attached). Any help would be appreciated.

Thanks

A new BSOD (INTERRUPT_EXCEPTION_NOT_HANDLED) just now; while I was away from my PC. I had Revit 2015 and Outlook 2003 and Google Chrome running. I had recently (since booting up today) cleaned the SSD via the standard Windows Disk Cleanup; not sure if this is the cause.

Attached the usual files. Please help if anyone is able.

In case anyone is interested, I have updated my Marvell 91xx SATA 6G Controller to version 1.2.0.1002 (7 March 2011) - which is listed as a BETA driver on ASUS Sabertooth drivers website - and so far haven't experienced a BSOD, but will leave it for another week or so to see if this has solved the problem.
