iastor.sys related BSOD

flightmedic · Sep 20, 2012

This started yesterday when I began having issues with Bitdefender.

Attached is the memory.dmp and the SF diagnostic file.

BSOD has occured during a recovery operation as well as randomly.

I have checked my SATA driver and it is up to date. I did go to the intel site and several other driver updates are available but I'm not sure if I should update them.

BSOD occurs randomly, sometimes as often as every 5 minutes.

Thank you for your time and attention with this issue.

iaStor.sys belongs to the storage drivers for the controller on the motherboard.
BUT, it also rears it's ugly head in a BSOD if you are infected with some variants of the TDSS rootkit.
There are other, less likely causes, but these are the 2 most common.

Try this free tool to see if you are infected with TDSS: How to remove malware belonging to the family Rootkit.Win32.TDSS (aka Tidserv, TDSServ, Alureon)? (it'll run in Safe Mode). If you are, and it still doesn't boot, you're in for some gyrations to get it to work (running multiple virus removal tools and multiple commands with bootrec and Startup Repair - that work in most (but not all) cases.

See if you can update the Storage drivers in Safe Mode (some installers will allow this) - and try the storage drivers from http://downloadcenter.intel.com to make sure you get the most current version.

We can troubleshoot this further, but if it's the rootkit you're best off with wiping the hard drive and reinstalling Windows.

To do this it's essential that you:
- backup your stuff (and scan it with an antivirus)
- find the restore disks for your system (not the restore partition on the hard drive)
- wipe the drive (to include all freespace) with either DBAN or KillDisk (both are free with a Google search)
- install Windows.

Thank you. I actually want to do a clean install of Windows 7. BUT, I';m having problems figuring out how to do it from a usb. I used the Windows 7 USB tool but when I get to "install now" I'm told there are no drives available to install it on. I was stuck doing a recovery operations from f11, though this was less than perfect for me.

I actually went to the download center and it told me my storage drivers were all up to date, but there were other updates available for other hardware.

Going to continue research and try to get this figured out. Thank you.

Those are the tutorials that I used. I get it as far as "install now" after it boots from the usb. When it asks me where to install the OS, there are no drives found.

koolkat77 · Sep 21, 2012

Where did you download the copy of windows 7 from?

flightmedic · Sep 21, 2012

The link in the tutorial.

essenbe · Sep 21, 2012

Are you running Raid and what is your sata controller set to in bios?

flightmedic · Sep 21, 2012

Essenbe, honestly I don't know. To either question.

gregrocker · Sep 21, 2012

Check for newer BIOS update on the Support Downloads webpage for your model. http://h10010.www1.hp.com/ewfrf/wc/document?cc=us&dlc=en&docname=c00034791&lc=en&product=3744230

Enter BIOS setup to check that your HD's are detected, reset BIOS to default, remove any RAID configuration, set SATA controller to AHCI mode, Save changes and exit.

Remove all but one HD and any peripherals.

Trigger installer using one-time HP Boot Menu by tapping at boot the ESC or F9 key.

If HD isn't seen wipe it with Diskpart Clean Command, then if necessary create, format and mark Active an NTFS Primary partition as shown in Step 2.2 in SSD - HDD Optimize for Windows Reinstallation

Follow these steps to Clean Reinstall - Factory OEM Windows 7.

If you have files to rescue do that before unRAIDing from the step in tutorial above.

flightmedic · Sep 21, 2012

I'm not quite sure how to change AHCI mode or remove RAID.

When I go into disk management there is C: drive, System (199mb/165mg free) and HP Tools.

Can I partition the C: drive and load the Windows 7 from the new partition and then simply remove the partition after the load?

gregrocker · Sep 21, 2012

Your Disk mgmt doesn't show correct sizes. How do you know you have 2x750gb HD's? If they're not shown separately in Disk Mgmt then they must be in a RAID array amounting to close to 1500gb. This can be problematic during a reinstall and is best unRAIDed.

Have you considered running HP Factory Recovery from it's partition after making disks for backup? However with HP's crushing load of crapware and duplicate utilities it is an inferior install, although you can mitigate it some with Clean Up Factory Bloatware

Please post back a screenshot of your maximized Disk Management drive map and listings:

1. Type Disk Management in Start Search box.
2. Open Disk Mgmt. window and maximize it.
3. Type Snipping Tool in Start Search box.
4. Open Snipping Tool, choose Rectangular Snip, draw a box around full map and all listings.
5, Save Snip, attach using paper clip in Reply Box.

Tell us what is on each partition.

flightmedic · Sep 21, 2012

System: Not sure what is on this
HP Tools: I assume this is the HP bloatware
Recovery (D)
Data (I

: second hard drive will be detached when I do the clean install.

essenbe · Sep 21, 2012

flightmedic, when you start the computer you will see the HP boot screen. At the bottom of that screen it should tell you what key to push to get into bios. It has to be pushed while still on the HP boot screen. Once in bios you should see a catagory called sata configuration, storage configuration or sata mode. Click which ever one you have and tell us whether it says IDE, Raid or AHCI. Also look at the boot options screen and tell us how many hard drives you see there.

gregrocker · Sep 21, 2012

You don't have a RAID configuration since there is a second Data drive for the other 750gb HD.

HP tools is bootable diagnostics and should be left intact if you want to keep the factory partitions bootable. Same with Recovery. If you're still contemplating a Clean Reinstall - Factory OEM Windows 7 then considerations about these partitions is discussed within, including Special Notes for HP Owners.

Are you inclined to run Factory Recovery or a Clean Reinstall? Either way I would make your Recovery disks first to have as a backup.

Download a new ISO and burn to DVD or write to stick using Step 1 and 2 in tutorial. Then boot, if HD is still not seen to choose partition, disable the data HD in BIOS setup to try install. If that fails you're probably going to need to wipe the HD which solves about half of these problems.

But read all of the tutorials again closely to know your various options, ask back any other questions you might have.

flightmedic · Sep 21, 2012

Would rather do a clean reinstall, to get rid of the HP bloatware.

I tried to create recovery disks but got the BSOD d/t iastor.sys so unable to create at this point.

I have the iso for windows 7 that was downloaded from the link on this site for a clean install. I also have the DVD/USB tool. Tried to burn to a DVD but again, BSOD. I'd really like to get to the usb method working or find another way to install.

Thanks in advanced for all the help to a nub like me.

Jim

gregrocker · Sep 21, 2012

Start over with the latest official ISO written to stick from Steps 1 and 2 in Clean Reinstall - Factory OEM Windows 7.

Reset BIOS to defaults, set SATA controller to AHCI. YOu may need to disable the second HD in BIOS.

If it still fails, wipe the HD with Diskpart Clean Command.http://www.sevenforums.com/tutorials/52129-disk-clean-clean-all-diskpart-command.html

How much free space do you have on your C partition?
Post the full Device Manager window, we might see something there that will help us.

HP bloatware is crashing.
Remove the HP programs if the BSoDs continue before you can re-install Win7.
