RAM (the temporary memory where your operating system, programs, etc are stored) stores bits as charge in a capacitor. Now this is where my understanding falls apart, so I'm going to take an educated guess and hope someone smarter corrects me: Random energy from thermal heat or stray cosmic particles can cause these bits to leak from the capacitor or for an extra charge be thrown into the wire as the data gets transmitted.
