HI my name is Tamir, Im a PC user like you, normally the manufacture website will have the driver you need but its sound like you have an older PC that is no longer supporter by the manufacture you can use a third party service call driver booster to see if it can find drivers for you and even look in the device manager and have windows do it for you
To update a device driver using Device Manager in Windows, you can do the following:
Open the Start menu and type Device Manager in the search bar
Select Device Manager from the search results
Find the device you want to update and right-click on it
Select Update driver
Click Search automatically for updated driver software
If Windows finds a new driver, follow the prompts to complete the installation
you can also click the option that say find hardware changes

the other option is to contact the manufacture and see if the have a driver packages disk or USB they can send you. With most Older PC when the manufacture stop supporting them there is not a lot of option to regain the driver outside doing a reinstall of windows and see if windows can install the drivers or see if a driver package is available most of the time you have to work without it.
