Hi

Please see if the following helps:

nvsvc32.exe is the NVIDIA Display Driver Service.

Disable it, it doesn't need to run.  I have had mine disabled for ages.

Disable the NVIDIA Display Driver Service...
Start | Run | Type:    services.msc    | OK |
Scroll down to and double click:  NVIDIA Display Driver Service |
Under Startup type set to Disabled | Apply | Click the Stop button |
When it stops click OK |  You may have to reboot

Disable Nvidia Services
When the Forceware drivers install on your system, they install a new
Service called the 'Nvidia Display Driver Service'. In general this service
doesn't have any essential functionality. In my experience, most people can
safely disable this service and not run into any difficulties or reduced
functionality whatsoever. In fact some users note that disabling this
service improves Windows startup and shutdown times and general performance,
so I suggest you disable this service. To disable it go to Start>Run and
type "Services.msc" (without quotes). This opens the Windows XP Services
utility. Double-click on the 'Nvidia Display Driver Service' and select the
Disable option under the 'Startup Type' box, then click OK. Disabled
services are removed from memory after the next reboot.

Note that some people report potential issues with temperature monitoring on
their graphics cards if this service is disabled, so check your temperatures
often and reenable this service (set it back to Automatic) if your card
usually runs extremely hot, or if you feel you are experiencing any other
strange behavior due to the disabling of this service. Once again though,
most users should be perfectly fine with this service disabled.

Display Name: NVIDIA Driver Helper Service
Service Name: NVSvc
Process Name: nvsvc32.exe
Dependencies: None
Need it? How did it get there? (Vital, Yes, Maybe, No, Not Installed,
Never):

No. This service is installed when you change from the WDM drivers to
nVidia's latest and greatest version. The service uses about 945k and zero
CPU. I have even experienced EXTREME shutdown delays with this service
active, but no adverse side effects with it disabled unless you override
your refresh rate. This service is required to override monitor refresh
rates in OpenGL games. In DirectX games, you can disable this service and
run "dxdiag" and override the refresh rate there. NOTE: If using drivers
other than nVidia's, such as Asus, this service may have been renamed to
reflect that.
