Before We Begin… 

If you are anything like me the first instinct whenever you get any kind of computer error is to fix it as quickly as possible. It is even tempting just to try different things out without checking any instructions of any kind.

Although I have often felt that same temptation, it is not something that I would recommend at all.

My suggestion is that you only attempt to fix the error after you have read through this article tutorial. Why? Because, apart from the preliminary checks that you will need to carry out before you can fix the error, you will need to make sure that you are in a position to fix the error. The last thing you want is to get through half the steps just to find out that you are not actually ready to finish the process successfully.

Check Your Drivers

So, before we can go anything further with fixing this error you should always check your drivers. It is likely that this error has been caused by the failure of one of your drivers.

How do you know if you this error has been caused by the failure of one your drivers? There is one way of writing this out, which is by making sure that your drivers are up-to-date.

If you do not know how to do this, do not worry. All you will have to do is to run a Driver tool.

There are many different tools available for free on the Internet. I will not recommend any specific tool but if you do not currently use one, you could head to Google search or any other search engine of your preference. Just search for a driver update tool online. Once you have downloaded and installed the tool, you should launch it and scan your drivers.

The tool will then scan all your drivers. Once your drivers have been scanned, you will be presented with a comprehensive list of all the drivers that need updates. If you have a Pro version of the tool, you will also be able to download and install all of the updates there and then.

If not, you would need to update each and every one of the updates yourself. This might take some time (depending, of course, on how many drivers actually need to be downloaded) but it is something you will need to do.

As a general rule, you should carry out driver updates frequently. This will avoid all kinds of different computer problems.
