Read this if you are having trouble running NXT and are unable to update your Intel drivers (and have already followed the instructions in the "Ready for NXT-Drivers" thread).
This post will only be useful for people that use Intel graphics as their main graphics device. If your computer has two then this is not recommended, as the other device will likely be your main GPU for gaming. Also, the issues this is most likely to fix would be graphical corruption and other graphics issues. It is not likely to help with caching, loading, sound issues etc.
It has come to our attention that some people with Intel integrated GPUs are having trouble updating to the latest Intel drivers. The symptoms are that you are told your graphics drivers are out of date, but when you try to update them, you are told there are no newer ones to update to. This appears to be happening because Intel allows some computer system manufacturers to ship PCs with altered versions of the official drivers. The purpose of this is to allow them to add extra features, but unfortunately the manufacturers do not always go to the effort to keep their drivers in sync with the latest Intel ones, so they drift out of date and do not get the latest updates.
There is a solution to this, and that is to uninstall the manufacturers drivers and install the official ones. There are instructions on how to do this here:
Note however, that doing this is at your own risk. Intel say you "risk losing functionality and causing other technical issues", and it's very hard to predict what these will be, if any. Most likely if your PC manufacturer has added any extra features you will lose these. The benefit is that you should be able to update to the latest drivers and get the latest fixes and updates from Intel.
