I cannot identify the chip or its function, you pics are good, the fire burned the markings. You should probably be concerned. Is the system functioning properly?
System's been running fine, I opened it today because it was emitting a crackling static noise through the speakers. Last time it was opened was when she got the computer maybe 18 months ago, so it could be relatively new or very old. I was afraid to power it back up after that, just because I was afraid it was a potential fire hazard... She uses this PC on her television for Hulu and such, so it stays on a lot.
