I am trying to install a new driver for one of my devices and I am having some trouble. Once the driver, an NVIDIA Ethernet driver, is installed for the NVIDIA nForce Networking Controller, the "svchost.exe" program begins to hog CPU resources on all four cores (20-30% usage). When the driver is not installed, the program does not behave this way. I have tried a few different driver sets all with the same result. I am using WHQL driver sets. What should I do?
