Use the search function to find the driver you need

Many hardware names are usually named after the chip model, and each chip model has its own dedicated driver, so as long as you know the chip model used by the hardware, you can find the right driver. For example, if your graphics card is named: "AMD Radeon RX 580", while actually the core chip model used is: "Radeon RX 580", then enter "Radeon RX 580" or "RX 580" to find the driver.

If you have a laptop or an all-in-one PC, you can also use the product name to search, and then go to the download page which has all the drivers for this machine (including: graphics card, network card, sound card, etc.). For example, if your laptop product name is: "Dell A6-9220e Inspiron Flagship", then type "Dell A6-9220e" to find all the drivers for this laptop.

Search steps:

1. Enter a keyword in the input box and click the "Search" button

2. In the query results, find the driver file you need, and click the download button
