Blue screen of death ¶ 

Your computer experiences a fatal system crash and can no longer operate safely.

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. If you have a restore point, try to load it and see if it helps, it may or may not.

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. Easy parts to check are the RAM and Hard Drive. You can find guides for those here and here respectively.
