The question comes in many different forms, and the answers can vary. Some people know they have a faulty graphics card but need clarification on what is wrong with it. They want to see if they even need a new graphics card or if they can fix the problem themselves. They may also be wondering what video drivers they should install on their computers to get better performance. To help you answer these questions, there are some troubleshooting guides that you can use when you need them.
If you cannot connect to your monitor (with either the system monitor or Windows), it is a good idea to check whether your monitor is plugged in correctly and turn it off and on again if necessary.
Try this…
Go into Device Manager (or restart your computer for short periods). Find and select the relevant entry for “Display adapters.” You should see a green arrow next to it or two other options: “Updates available” or “Installed updates.” If there is no green arrow, start checking things out from this point…
Check that your driver has been installed correctly (see below). Try switching from one display adapter type to another, for example, from DVI-D-to-VGA. The possibilities are pretty much endless here, so make sure you check everything before assuming there is something wrong with whatever type of display adapter you have first tried out using a different kind of cable/adapter, whichever option works best when you boot up your machine as this will affect how well RAM will work as well as how fast the screen will refresh itself, etc.
If you are having problems with settings changes on booting up, try installing the latest drivers by running the command: Sudo apt-get install server-Xorg-video-intel. If this doesn’t solve any issues, then take note of all details relating to which settings got changed by restarting.
Try this.

A common problem with Xfinity is that video streaming or recording won’t work. This can happen for multiple reasons, but the most common problem is your Internet connection.
To fix this issue, you must have an internet connection before recording or streaming anything on your computer. If there isn’t any kind of service available, then it’s likely because someone else has already taken over their modem. You’ll have to call them and ask if they can give you access, so they don’t lose out on potential revenue from customers who want live TV!
