SOLVED!!!!!
I know this thread is wicked old but this issue has plagued me for a very long time and I have finally fixed it across all platforms and for all Hardware!!!
I am posting this fix because there is absolutely no legitimate fix on the entire web that is a true fix and to help anyone else having this annoying issue; especially gamers and NVIDIA MOBO and Graphic Card owners, so here it is (FINALLY!!!):
EventID - 129
Source nvstor, nvstor32, nvstor64
Reset to device, \Device\RaidPort2, was issued (this is one of many messages you may receive)
If for any reason the Registry entries below for the fix don't match your system, search the registry for nvstor and the "like" keys on your own system
The fix is in 3 places on my system so navigate to each one, one at a time
HKLM\SYSTEM\CurrentControlSet\Enum\PCI\VEN_10DE&DEV_037F&SUBSYS_C55E10DE&REV_A2\3&2411e6fe&1&70
You will see a Sub Key named "Properties" which should throw an inaccessible permissions error, take Ownership of it and give your account FULL ACCESS only for that key but uncheck subcontainers and objects
Do the same for the following 2 locations (you may want to search to see if you have additional, similar keys but I only had 3 total):
HKLM\SYSTEM\CurrentControlSet003\Enum\PCI\VEN_10DE&DEV_037F&SUBSYS_C55E10DE&REV_A2\3&2411e6fe&1&70
HKLM\SYSTEM\CurrentControlSet004\Enum\PCI\VEN_10DE&DEV_037F&SUBSYS_C55E10DE&REV_A2\3&2411e6fe&1&70
You may or may not have to reboot
After you do this and recheck the keys you will see that they have populated the subkeys with LOTS and LOTS of New Data!!!!!
That's it, FIXED! You will not have access permissions to any of those keys but that is fine.
I have also found that in the nvraid.inf config file it there is an explicit permission for "Administrator" (; allow access from system and administrator only); whether or not you have access to the "Properties" key under the Administrator Account is irrelevant, the issue will not be fixed unless you follow my steps above.
I really hope this helps a lot of other people because this issue was a doozy!!!!!
Best of luck,
