"Install the drivers from the official support page..." if a specific support page no longer lists or carries the drivers for an older laptop, then first and foremost make full image backups, onto external media, of the OS. Then and only then would I recommend an outside source for a necessary driver or drivers. For example, I have used Auslogics Driver Something after making backups.
Helpstar and WilliamD both make excellent points! I had to go the 3rd party route only because technical support for my laptop, which was converted from Windows 8 to Windows 7 by a local computer store by my request, did not have Windows 7 drivers for that particular laptop, it was shipped with Windows 8, and therefore the official web site only had Windows 8 & 8.1 drivers.
