Did you have an Installation CD for the motherboard? If it's a 'name brand' computer, did you use the Revocery Cd or whatever other means was provided to restore the PC to its original state?

If it's a name brand PC what is the make and modsel number please? If not, what is the make and model number of the motherboard? The drivers are obtainable from the manufacturer websites.


If all you have done is to format and load Windows again, then your system is most likely using 'generic' drivers for its components, which may not be providing full functionality.
