If you can’t find drivers for your old computer or if the manufacturer doesn’t have updated drivers, try going to the Chipset manufacturers website.

Intel

The Intel website will detect what system you have and list your processor, chipset, RAM, hard drive model and it will tell you if there is any Intel software that needs to be downloaded.

AMD

Even though AMD says they have an autodetect page it doesn’t exist and if it did, it will only detect what graphics driver you have.

find what type of chipset the computer has and select it at the bottom of the page
