Find Windows Missing Drivers/ Yellow Exclamation Mark on it. it is a very common issue with the Windows, especially when you install a new Windows. One way is to use a third party driver pack and install all missing drivers but sometimes it will make the case worse, by installing universal or old version of drivers for your hardware which will not work correctly. The best way which I follow is by installing drivers individually from the drivers support website of the hardware’s vendor e.g. HP, DELL, SONY, TOSHIBA, ACER, ASUS, FUJITSU, and many more. But to install individual drivers you need to know which driver you are looking for.

Well this why I am posting this tutorial, to find the name and brand of the missing driver so you can download and install it from Vendors’s driver support website. Below I share a picture of my laptop and I have a “PCI Device” driver missing. The process is same for “Unknown Device” as well. So lets find out the driver with the yellow exclamation mark on it.

PCI Lookup is a database for Vendor and Device Ids. You can find the name of your missing or Unknown driver in your laptop. As you guys can see in picture below the result of PCI Lookup database and check the description. My missing PCI Device driver is actually a card reader driver RTS5229, and the vendor of this card reader is Realtek. Now its very easy to find that driver and install the missing driver.

Remember always try to install your missing drivers from your hardware’s Vendor, if you try to install it through a third party website you will most likely get the old version driver with virus.
