USB Problem
Last week I have formatted and installed Windows 7 Professional. After 2 weeks of my PC working perfectly, there are two problems:
1) I have installed Nvidia Driver in order to change the Brightness, Contrast etc by right-click on desktop and choosing Nvidia. The problem is everytime I reboot the Nvidia driver looses the settings.
2) My CPU is always at 100% without any applications open or and other software running the in the background
3) I bought a new USB Hub and sometimes it works and sometimes not - connecting pen drive and other devices, Windows states USB DEVICE NOT RECOGNIZED etc.
Is my motherboard malfunctioning?
Thanks.

The HUB is powered. The CPU speed seems to have stabilized.
Do the devices work when plugged in directly?

Yes. The HUB is brand new.

1. USB Problem:
When I connect my pen drive to the hub nothing happens, when I cannot it directly to a USB connection it works.
2. CPU: When I run Google Earth it takes 83% of the whole CPU. In the past it did not consume such power.

and you verified the hub is not faulty, and working ok on ALL ports?

Any other apps taking high percentage of CPU?
