Hi there, long time reader of the forums, but first time posting today.
Just cracked open my mom's PC today for a sound card issue, and found a rather significant burn mark, from what looks like to be a fried chip, or something. I would assume she's had it on there for a long time. Is this something I should be concerned about?
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.
power down and disconnect the power supply. hit the power button to drain any left over power.
Clean the area with rubbing alcohol and a q-tip(gently) make sure there is no other damage to the board.
I had a board with blown caps in the usb system and it(the board, not the usb ports) worked fine for years.
chances are good it will run for years like that. I guess the case is a tower style(is it?) and that is why the burn marks extends up. if it was a desktop style case, the chip would have just melted/burned it self without burning the board.
