NVSvc.exe NVSvc32.exe
(NVIDIA)
NVIDIA Driver Helper Service which gets installed under Windows NT4/2000/XP by the NVIDIA drivers for some of their graphics cards (or graphics cards based on an NVIDIA chipset). We do not at this stage know what this process does except consume memory ! And we also have no idea as to what a "Driver Helper Service" is supposed to do !!
Recommendation :
This service is often responsible for various glitches, from significant shutdown delays to excessive memory usage. Disabling it, however, does not result in any ill-effect as regards the proper operation of your NVIDIA or NVIDIA chipset graphics card, so we recommend that you definitely disable this service via "Control Panel \ Administrative Tools \ Services" ("Control Panel \ Services" in NT4).
