Those two files are part of your Nvidia driver :-)

Info on nvstor.sys:

Info on nvstor32.sys:

I also found this in the Nvidia forums:

Quoting from the relevant post from the Nvidia forum link above - highlighted the relevant part in bold:
NVIDIA had changed the names for their S-ATA and RAID drivers. NVSTOR.SYS is the name of Vista's in-box nForce S-ATA driver (32/64bit), the actual 32bit Vista S-ATA drivers are named NVSTOR32.SYS, whereas the 32bit nForce RAID driver name now is NVRD32.SYS (formerly NVRAID.SYS).
In other words, nvstor32.sys indicates your bit system. If you had a 64-bit system, it would be nvstor64.sys.

Win 7 Ultimate 64-bit. SP1.

Both file names & descriptions are below.

nvstor32 > nvstor32.sys > Related to nvstor32.sys NVIDIA® nForce(TM) Sata Performance Driver.

nvstor > nvstor.sys > Related to nvstor.sys nForce(TM) Sata Performance Driver from NVIDIA Corporation .

They are legitimate.

More details are needed re the error you receive.

*Have you checked in Event Viewer?
Type eventvwr in search.
Go to the windows log>application tab.
Look for critical errors (they have red in the left column)that say anything that relates to this particular "problem."
Please note the event ID, and the source codes.
