Haven't found the right driver yet? Are you facing difficulties in the driver search process?

1. The drivers you found aren't compatible.

2. You don't know how to search for drivers.

3. Your device isn't installed with drivers and appears as an "unknown device" in the system. You don't know how to find drivers for it.

This website offers a new method for finding drivers, a precise and fast way. Click here to use the new feature.
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

Driver Finder:

• Can't find the required driver files?
• Don't know how to find driver files?
• Unable to download driver files due to unstable network?
You can try using this driver file finder. The method of use is very simple. The program will automatically list all the driver files available for your current system. You can install drivers for devices that do not have drivers installed, and you can also upgrade drivers to the latest driver version for devices that have already installed drivers. Click here to download the driver finder.

I brought a second-hand computer from a friend. When I press the power-on button, the indicator on the case is off, and the power supply fan is just shaking in place. I guess the power supply is broken. How can I repair it?
 AdminReply:
This situation may be caused by a wrong power switch setting on the motherboard or a power failure. As the motherboard of some old computers has a mixed structure of AT and ATX, there is a power switch on the motherboard. If the motherboard uses an ATX switch, but uses an AT power supply, such a failure will occur. At this time, you should check the setting of the motherboard power switch type. In addition, if the power supply voltage is particularly low, this phenomenon may also occur. You can use a multimeter to check whether the output of the power supply is faulty.
