How to find which driver are support on unknown brand motherboard

Hello you can download the driver here:

http://www.asus.com/Motherboards/AMD_AM3/M4A77TD_PRO/#download

Please select your windows system 32 or 64 bit.

Open the driver folder by click on +.

And download the driver by click on the global link.

Unzip the file before you install it.

Unknown device could be a missing chipset driver, card reader, sound card etc.
Try to install the drivers one by one and the unknown device should go away.

Remember to reboot when you asked to.

Good luck

The best would be to know the brand of pc and the model, the MB came from. Then go to the brand website support section, and download the drivers for that model.

If that is unknown, then the next easiest way is to use one of the many new driver sites that have sprung up, in which you down load and install a utility which then downloads all the latest drivers for your machine. Like this one..

If you just google "drivers" you will find 4 to 8 similar places that do this. Personally I am wary of these, and I suggest you read the fine print before agreeing to installation. BUT they will probably work for you.

this link helps to figure out all the required drivers for the motherboard of any computer

If this is the original motherboard in the computer,

• Find your original drivers cd for the computer and install all those that aren't working.

If you can't find that CD.

• find the model number or computer tag # and go to the website for the computer brand.
• Dell.com, gateway.com, hp.com
• find the computer support page and search the tag or model number. Look for a page regarding drivers and support.
• You should find the drivers for you. You might have to use another computer and put the driver on a flash drive.

If those dirvers don't work, you have a damaged motherboard or something has failed. Please write back if you have exhaused those options.

If you have the motherboard CD the Vista drivers should work in Windows 7. Try updating the drivers for the two unknown devices from the motherboard CD. If you don't have the CD you should be able to download the USB chipset drivers from your motherboards manufacturers website.

You can try this small application (http://www.cpuid.com/download/cpuz_150.zip), just unzip & run it and you'll see the details and the brand/model name of your CPU, motherboard and memory. And also for other hardwares (like graphics accelerator, network cards, ...) you can install and try this application (http://www.cpuid.com/download/pcw2008_v1871.exe) to get more detailed information about your computer's hardware. These applications are very simple and easy to use, I think it won't take too much time to get the knowledge of your computer's hardware. After this step, you can go online and check the website of the each hardware's manufacturer's for their latest driver according to your operating system. I hope this helps.

is it a seperate sound card or is it onboard, if it's on board let me know the motherboard brand & the model. if it seperate. chances are that you will have to use something like driver checker, where it will automatically download the driver for you.

right click on the unknown device and update driver choose search for th edriver automaticallty then you'll know what is missing

If your PC is a branded one, like Dell Acer , HP, Packard bell, IBM, etc, then we can find the drivers by looking at the PC model number.

If PC is not a famous brand, you will need to remove the PC side panel, look inside the PC and write down the ID numbers printed on the motherboard.

Then post a new question on Fixya giving details of the motherboard number, so that we can find the right driver.
