First, prepare the system. Take care of cooling the processor Athlon. Install a powerful fan for the timely heat exchange with the external environment. Sometimes extra 10-15° C reduces the working resources of this processor in two and more times. Therefore, good ventilation is essential. In rare cases, enthusiasts even cut off the top part of the system case and install another cooler to supply cool air to the main fan.
Identify drivers and Woo your system. If the databases are obsolete, download via the Internet from the website of the manufacturer of required packages files and pre-install them.
