Faulty capacitors are causing video failure and periodic system shutdowns in some Apple G5s. The red arrows points to several swollen capacitors on the back of this new iMac. (Not all of the capacitors are bad). When functioning properly, capacitors temporarily store electrical charges and release them as needed.
