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

Replaced avast! with MSE successfully. Clean boot through CCleaner (screenshot included). Froze (iaStorA.sys BSoD) after 5 or so minutes. I've had enough for the day, haha. Bedtime for me.

Strangely enough, it really only seems to BSOD when connected to power. I've been running off the battery for about 2 hours now, and nothing ominous has happened. I took a peek around the net for similar symptoms. There were quite a few, but their freezes were either immediate (mine are not), or not BSODs at all (mine are). One guy solved his problems by making his "power plan" the same for both the battery and ac power. I did that as well, but it didn't solve it.

I'm not a real great Laptop person, but they are still computers. But, some differences in them. Does your laptop have some type of HP optimized power plan? I have a Samsung laptop which does. I really don't use it, but it has one and I thought that may help.

HP, like most PC mfgrs do not ship discs, they give the user the method of creating one set of install media. Either the discs or the Recovery partition can be used to recover from a severe system failure.
Creating Recovery Discs or Saving a Recovery Image to a USB Flash Drive (Windows 7) | HP® Support
Having both the HP install media and the plain vanilla install media (created from the downloaded ISO) is a good strategy.

Yessir. I am running off the HP Recommended power plan. I suppose I should be more on the ac power, but since the BSoDs started, I just charge it at night and run it off the battery for most of my use during the day.

I've just been looking and it seems this is a common occurrence, just the responses are different. Some are graphics related but all are while on power brick. I find a lot of complaints but no solutions, yet.

Hi dysphoria,

I have an HP dv6-c610us laptop. It's always 'fun' trying to find stuff on HP.

I did discover what CTO means though - Configure to Order. This brings up questions re: RAID.
Did you order the machine configured with RAID.
Is this a refurbished machine?
Did you make any changes regarding ACHI, RAID, or legacy.
When I tried to locate information for your machine, it took a while - and that's not even looking for drivers, just the machine.
Reference docsThere is also a QUAD edition, but the product number in both URLs are the same. In a post on Tom's hardware, a user identified the product as A3F49AV, so I don't think this is the machine you have (post# 23, product A3E83AV)

There are some interesting notes on this thread
  • No IDE in Dev Mgr
    I'd like you to try this
    Right click Computer
    Select properties
    Pick Advanced System setting in the left hand panel
    Press the Environment Variables button (lower right)
    The upper section is User variables
    Press the User variables New button
    Enter the following in the field boxes
    Variable name: devmgr_show_nonpresent_devices
    Variable value: 1
    Press ok

    Then open Device Manager
    Click the View menu
    Pick Show hidden devices

    Post a screen shot of the top most level of Device Manager
    If there is a ghost (light grey icon) IDEATA/ATAPI category, expand that and post a screen shot
  • fewer less frequent BSODs when on DC only
    See this to inspect and verify the adapter is correct for your machine (was it replaced at any time)
    Using and Testing the AC Power Adapter

Thanks,

Bill

Forgot a few questions

Is the laptop in a docking station?

How long does the battery last after full charge?

How does the PC behave/perform if you remove the battery and run on AC only?

Thanks,

Bill

Hey Slartybart!

I did custom order my laptop, yes. Not refurbished; brand new.

Here are the specs from my order that I saved...hopefully that helps.

YOUR CUSTOMIZED HP PC

• 8GB DDR3 System Memory (2 Dimm)
• 750GB 7200RPM Hard Drive
• 32GB mSSD Hard Drive Acceleration Cache
• $40 OFF Microsoft(R) Office Home and Student 2010

As for the power supply...

It has never been replaced--I am still using the original adapter that was issued.

"Is the laptop in a docking station?"
No.

"How long does the battery last after full charge?"
Possibly about 4-5 hours if I turn the brightness down. Around 2-3 with full screen brightness.

"How does the PC behave/perform if you remove the battery and run on AC only?"
Never tried that one, actually... Will give me something to do tomorrow! I'll also check out your link, "Using and Testing the AC Power Adapter".

I wanted to say that about a month ago, I ran a battery test in HP diagnostic mode (I forget the exact name, but it wasn't BIOS). Anyway, the battery tested fine then.

Thank you K - the feedback you provided is great.

When you get the chance, could you expand the Other Devices in DevMgr? (view menu - show hidden. You don't have to set the variable again though, it's already defined)

I can't see where the RAID comes from, even considering
750GB 7200RPM Hard Drive
32GB mSSD Hard Drive Acceleration Cache
that's going to take more research.

I think what happened is the IDE ATA configuration got buried somehow and it's going to show up under Other devices (to be honest I expected it to show up as a ghost entry). Once (if) you find the IDE controller device, I think it's just a matter of reconfiguring, possibly reloading the driver. But don't change anything yet - more investigation is required to do it correctly without causing more issues.

I'll take a look at what HP offers as drivers - that always gives me a clue on where to start.

Please post the results of the AC / battery removed test - it might take a few days (ha - no BSODS would be great)

Bill
