As we already learned, this error often is caused by outdated or corrupt drivers, therefore you will have to update them. The key here is to find out which driver is the faulty one and needs to be updated. So do what ever you do and wait until the error occurs once again. Then write down the faulty driver’s name to find out what does it do. Once you know your faulty driver’s name, do a research about it. Find out whether it’s Windows or hardware driver. You can do this by using online websites. We used Carrona because it’s easy to use and is very straight forward. See link below:

Once you open this website, in the search box type your error. For example, driver’s name:”ndis.sys”. Once you find it, you will be provided with driver’s full description.corrona

As we already mentioned, there are two kind of drivers – hardware and Windows related. You can tell what type driver is yours in the “Source section”. If it has links, it’s hardware related, if the source section features lettering of “Windows update,” it’s a Windows driver. See image below:Two different drivers

Now you probably know whether your faulty driver is windows or hardware related. Let’s see the difference between them.

Hardware drivers
Hardware drivers are used to run certain hardware of your system. Not only external but also internal hardware like motherboard, video card or network adapter. There are like a conjunction between the operating system and device.Drivers

Windows driver
Windows drivers are used by your operating system. They ensure Windows is running correctly and there are no issues.
