From the submitter: My new video card is rather LARGE, and there was only one slot on the motherboard which could accomodate it. It’s VERY close to my sound card (which also cannot be moved), and I noticed a strange “ping..ping..PINGPINGPING” sound coming from the case. All the heat generated inside was making the entire video card warp slightly (this only occurs when playing Fallout 3 with LOTS of mods) and the fan was coming into contact with some of the solder points on the sound board! Yikes! He had problems with overheating so he decided to fix it with little pieces of plastic
