From time to time, you may need to use the built-in Recovery function on your PC to get it working after a virus infection or accidental deletion of a critical system file etc. After doing this, you may find that some of your system device drivers are not installed correctly, and this will result in your system under performing. To check that all of your drivers are installed correctly, you will need to open up your Device Manager - Click Start > Right click "Computer" and select "Properties" > Click "Device Manager". This will show the Device Manger window -
Notice that the USB controllers have yellow exclamation marks next to their device pictures, indicating that the drivers are not installed for these devices.
First, we will try and let Windows find the the drivers automatically by searching online for the driver software -
Right click the device with missing drivers and select "Update Driver Software...". Now select "Search automatically for updated driver software". (You must be connected to the internet.) Windows will now search online for compatible driver software for this device and install it. Windows 7 and Windows 10 are very good at doing this, and you will usually find that this method works. However, in some cases Windows will fail to find the correct drivers for your device and you will need to visit the computer manufacturers website to obtain the driver software.
Most manufacturers have the same path in which to find the drivers for the system, and will usually involve going to the support section, then drivers, and then selecting your machine from the various options.
Also note from the Device Manager example picture above that under "Display Adapters" it shows "Standard VGA Graphics Adapter". This is a generic, low performance driver for your graphics card/ onboard graphics chip, and will result in poor performance with video playback and games. Again, you can try the automatic method above to find the drivers for this, but if you have purchased a gaming system from us it will mean you have a dedicated graphics card installed and you will need to visit the manufacturers site to obtain the drivers (usually NVIDIA).
