it could happens on he top of it .
1 more thing, it was more like a pop. It sounded like a bridge creaking or something stretching for a quik "k" sound. It can also sounds like the wood "poping" in an old house. Kind of like if you sit in a room for awhile and you hear a pop. I wasn't very loud though.Maybe you guys thought that it lasted for awhile, it actually lasted for a quick millisecond like a not too loud POP. If it is a broken capacator, how could that have happened? I have a very high quality surge protecter and my temps are low. My motherboard is a gigabyte z77-Ds3h and PSU is antec 750w high current gamer.
