Error code 0020 is coming from a capacitor loose OR ALMOST ABOUT TO BE LOOSE! This means when you got to the green lights for a recent time, the capacitor touched the mobo! This is not the exact capacitor yours might have... but the capacitor could almost be loose. This photo is claimed by someone else that got error code 0020. My capacitor was the smallest capacitor so I am not lucky to put it on there good. I tried the heatgun but it seems that its not hot enough... tried the soldering iron but it finally fell off... HOPELESS... any ideas?

Error code 0102: This error is caused by a cold solder joint under CPU, GPU or one of the RAM bricks. Photo is NOT CLAIMED BY ME! Just to get the idea...
