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?
