Potential fix for Nvstor.sys, Nvstor32.sys errors.

Good day all.

I'd thought I would share my good news.

I have had the dreaded "nvstor.sys", and "nvstor32.sys" problems for the last week. I have tried every trick I could Google for. I tried newer drivers, and older drivers. I could also reproduce the error (at will), so that it would show up in the "Event viewer". Not a thing would work.

I am running Windows 7 (32 bit), Nforce 520 board. I installed this hot fix (Windows6.1-KB982018-x86.msu) "http://thehotfixshare.net/board/index.php?autocom=downloads&showfile=12386" which updates your "nvstor.sys" to version "10.6.0.18". That helped but did not fix the problem. Instead of errors in "nvstor.sys", the errors started showing up in "nvstor32.sys".

The fix: Make sure your sata boot drive is the on the first sata port on your board. My boot drive was on the second port. As soon as I put in on the first port, all my problems went away. I could not reproduce the error, or get an error in "event viewer".

I'm not 100% that this will work for everybody, but it fixed my problem. I've been messing with this for over a week now.

I'll post back if I start getting errors again, but I think this fixed it.

Good luck to everybody that has this problem. It is a headache.

This worked for me!

Was trying to fix for a mate, grasping at final straws with an intermittant hard crash problem, and switched the sata drives on a whim.

It fixed it and I was most confused as to why this would work.

Then found friends crash log and located the nvstor driver

found this page

Shot away!

nvstor32.sys and nvstor.sys are part of the nVidia chipset for your motherboard, it could be due to problematic drivers or a bad motherboard.

Anyhow, thanks for posting, the solution which has worked for you.
