To prevent the blue screen, which is likely caused by a lack of RAM, you should "strip down" the amount of applications running on the system. Press and hold the windows key, press "R," type "msconfig" and press enter. Navigate to the "startup" tab, un-check the box next to everything that doesn't need to be running when the system starts and press "apply." Now restart the system.
The blue screen produces an error code. Running the code through Google may provide information on the problem and enable an easy repair. A common cause of the blue screen is lack of power within the system. Unplug any device from the computer that doesn't need to be plugged in, such as extra mice, USB speakers, printers and game controllers. Another alternative is to upgrade to a more powerful power supply.
Blue screens are sometimes caused by out-of-date drivers. Navigate to the PC manufacturer’s website and download the latest drivers for the computer. Install them and restart the PC. To further prevent the blue screen, clean up the system. Uninstall unwanted applications, delete unnecessary files, perform a de-fragmentation and check the hard drive for errors. To do this, navigate to "computer" and right click on the main hard drive. Select "properties" then select "tools".
Blue screens are often caused by faulty RAM. There are free tools to check the RAM for errors. A fool-proof way to stop the blue screen is to replace all of the RAM, upgrade the power supply, re-install Windows from scratch and install the latest drivers. After these steps the blue screen should not appear again.
