BSOD at random levels of usage

happens sporadically, during high and low usage. this most recent one occurred while the laptop was left idle. can anyone help? attached minidump files...i think.

Code:

BugCheck C2, {7, 109b, 70021, fffffa8007d95ee0}

*** WARNING: Unable to verify timestamp for iaStor.sys
*** ERROR: Module load completed but symbols could not be loaded for iaStor.sys
GetPointerFromAddress: unable to read from fffff8000330c100
GetUlongFromAddress: unable to read from fffff8000330c1c0
Probably caused by : iaStor.sys ( iaStor+3fc66 )

Code:

Usual causes:  Device driver, Memory

This bugcheck indicates that a device driver has attempted to free the same pool allocation twice.

Code:

1: kd> !pool fffffa8007d95ee0
Pool page fffffa8007d95ee0 region is Nonpaged pool
 fffffa8007d95000 size:  c00 previous size:    0  (Allocated)  NDw1
 fffffa8007d95c00 size:   30 previous size:  c00  (Allocated)  ReSe
 fffffa8007d95c30 size:   90 previous size:   30  (Allocated)  Vad 
 fffffa8007d95cc0 size:  210 previous size:   90  (Allocated)  CcSc
*fffffa8007d95ed0 size:   70 previous size:  210  (Free)      *NvCp
        Owning component : Unknown (update pooltag.txt)
 fffffa8007d95f40 size:   c0 previous size:   70  (Allocated)  FMsl

The pool page (non-paged pool) isn't corrupt which is good, the * points to the address of the allocation which was double freed. The pool tag is not documented within the pooltag.txt file, however, similar pool tags point to nVidia, I'm guessing it's associated with the nVidia Control Panel?

Your Intel Rapid Storage driver seems to be causing problems, please remove completely with these instructions:

Arc said:

Get rid of intel rapid storage. First uninstall it from Control Panel > Programs and Features. Then Uninstall the driver from device manager.

1. Right click on "my computer" icon and click "manage" on the context menu.
2. It will open the "computer management" window.
3. Select "Device Manager" in the left pane, It will list all the existing devices up.
4. Expand "IDE ATA/ATAPI controllers" by clicking on the triangle in front of it.
5. Select one Intel device item under it, right click, uninstall.
6. Continue the process for all Intel items under "IDE ATA/ATAPI controllers"
7. Now restart the computer. At restart, windows will auto configure the appropriate native system driver.

Code:

1: kd> lmvm iaStor
start             end                 module name
fffff880`01857000 fffff880`01bfb000   iaStor   T (no symbols)

thanks for the reply, x BlueRobot.

i can uninstall intel rapid storage, but I can't seem to locate "IDE ATA/ATAPI controllers" in my device manager. i'm not too great with computers, so i'm wondering if steps 4-6 would be for desktops. the blue screens are occurring on my hp envy notebook.

It applies to all computers.

yupp, it's not showing up in the device manager. i was able to uninstall the intel rapid storage, however. waiting to see if i get another blue screen.

Create a backup of all your important files and data, and then follow this tutorial for perfect install without Intel Rapid Storage - Clean Reinstall - Factory OEM Windows 7
