Determine if you changed anything recently. The most common cause of the Blue Screen is a recent change in your computer’s settings or hardware. This is often related to new drivers getting installed or updated. Drivers are software that allow your hardware to communicate with Windows.
- Because there are essentially an infinite number of hardware configurations possible, drivers can’t be tested for every possible setup. This means that sometimes a driver will be installed that causes a critical error when communicating with the hardware.
- Check your computer’s internal hardware. Sometimes, a poor connection inside the computer can cause a Blue Screen. Open your case and check to make sure that all the cables are firmly connected and that any cards are seated firmly in their sockets.
- This is more difficult for laptops. You can check the hard drive and the RAM to make sure that they are connected properly. Remove the panels in the back that cover the hard drive and RAM with a small Phillips-head screwdriver. Press the components firmly into their connections.
