First off, you need to check if your computer is simply overheating. You may need to clean your fans or get a new one.
However, if overheating is not the problem:
Check if your hardrive or any other computer components are loose.
You may also have faulty ram. If you have more than one stick of ram, try to take one out and boot up. Do this for each stick. If your computer does not BSOD with a certain stick not in the computer, that stick was probably causing it.
