Windows 10: Iastora.sys problem

So, I got a problem with bluescreen of death which appears sometimes when I work on my computer. It says "DRIVER IRQL_LESS_OR_NOT_EQUAL" and in event log it shows 0x000000d1 error. I see that this problem caused by intel rapid storage technology but I don't actually know how to fix it. I searched for broken drivers but system says it works OK. Also this error appears with different time periods because sometimes it may showup every 30 minutes, sometimes with 2 hours gap and even more. So, my guess is that I should update my Intel rapid storage technology drivers(which is wierd cause I didn't update it for long and everything was alright) or should I reinstall OS with deleting my personal files?

Windows 10 1709 System Restore problems...

That seems to be an attempt at Option 2 in the tutorial, which requires you to
a. Boot to a command prompt (Did you?)
b. You then seem to be mixing steps 3,4 and 5, thus your command is incorrect.

I suggest Option 1 is easier.

If you still have problems, please repost listing each specific step and saying which option from the tutorial you are using. Thanks.

What is semav6msr64.sys & Mellanox Drivers?


I noticed semav6msr64.sys on my system earlier today (also via Autoruns), and eventually tracked down the program which installed it - you heard it here first! It's an Intel file, and just coincidence that SEMA Software authored a driver file with the same name.

On my system the driver was installed by the Intel Driver Update Utility Installer, which I'd installed to update my Intel drivers. Uninstalling this program after use doesn't uninstall semav6msr64.sys, presumably due either to a bug in the uninstaller or to laziness of the development team who wrote it. I don't like leaving software package remnants on my system for no good reason, so removed it as follows:

1. Create a System Restore Point in case the following steps cause any problems.
2. Uninstall Intel Driver Update Utility Installer, if it appears in the installed programs list in Control Panel.
3. Rename semav6msr64.sys to semav6msr64.sys.bk [to be deleted sometime later if no problems are encountered].
4. If, and only if, you're comfortable editing the registry, delete the following keys (otherwise just leave them, they'll have negligible effect):

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_SEMAV6MSR64
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\semav6msr64
