Windows 7: BSOD referencing iaStor.sys. Running Win 7, 64-bit.

BSOD referencing iaStor.sys. Running Win 7, 64-bit.

Hello!

Running an HP Pavilion dv6 laptop w/Windows 7 Home Premium (x64).

I have been battling an iaStor.sys BSOD for about 3 weeks now. No specific action seems to trigger it, from what I can tell. Strange that it seems to happen more frequently when my computer is connected to ac outlet power as opposed to running off battery power.

I have tried System Restore to about 5 days back (at the time). I have scanned with MalwareBytes and avast!, and things came up clean. I updated my nVidia, BIOS, and Intel drivers...to no avail.

I am an average computer user--certainly no expert. I did use the DM Log Collector and attached my .zip file. Hopefully this helps!

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e)
This is a very common bugcheck.  Usually the exception address pinpoints
the driver/function that caused the problem.  Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003.  This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG.  This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG.  This will let us see why this breakpoint is
happening.
Arguments:
Arg1: ffffffffc0000005, The exception code that was not handled
Arg2: fffff88001073768, The address that the exception occurred at
Arg3: fffff88003be5868, Exception Record Address

Thank you, koolkat!

I apologize for the delay; I was wiped out by some kind of flu today. Tonight, I did manage to disable all my startup programs via CCleaner (which I've had for years). I also performed the clean startup via msconfig and rebooted.

Things are quicker, and no freezes/BSoDs yet. They are seemingly somewhat random, but usually happen anywhere between 5 minutes or 2 hours. If there are no freezes by tomorrow, I can be quite certain there is some kind of application conflict.

Thank you for a step in the right direction! A relief in frustrating times.

Well, I did end up having a crash this afternoon, but the interval between crashes was probably the longest yet. It seems that I cannot disable my avast! Antivirus. It doesn't allow me in CCleaner or msconfig. I'd hate to uninstall it altogether...

This was when everything (except avast!) was disabled.

Ideas?

I went ahead and ran the Kaspersky TDSS Killer. It was clean.

I ran the ESET Online Scanner a week or so ago, with a clean result. I'll go ahead and run it again just in case.

I will take a break now, before I attempt the Intel removal. I wanted to ensure that the only thing I would remove from the program list is "Intel Rapid Storage Technology", because the tutorial mentioned "applications"...and I do have about 12 Intel programs/applications listed. Here is a shot from my Windows program list.

In my Device Manager, I do not have "IDE ATA/ATAPI controllers" listed. I mentioned I am not entirely tech-savvy with these kinds of things! What category should I look into? Here is a shot from my Device Manager list.

That's the first time I have seen a Device manager without IDE ATA/ATAPI Controllers How about expanding Storage controllers and post a screenshot.
