best female usernames dating sites - Updating chipset
CPU-Z has two versions: a version with an installer, and one in a zip file.
Running the one with the installer is a little easier so just download it and execute it to install it.
Or if you don't like installers and declining included software then just download the zip file and unzip it.
In the exceedingly rare cases where CPU-Z doesn't work you can try Sandra Lite. CPU-Z uses the term chipset rather than northbridge.
Most chipset drivers come as a single unified software package which contains the various drivers for both chips.
