okay, the subject is a little off, I -know- I should be worried.
here's the scoop.
basically I have an old pc, celeron or something here, which I was
using as a media PC, to watch my downloaded movies on my tv, with s-
video out and such.
anyway.
since around when I put it together, I was getting little shocks
occasionally from it. I don't know what it could be. every time it
happened, I got the shock from the case itself. and each time I
quickly unplugged the computer. once plugged back in, it didn't have
any problems.
recently I haven't been getting shocks at all, but just yesterday I
turned it on, and it was running for a while just idle, and I smelled
burning, and then it froze. I quickly rushed over and unplugged it,
and looked inside, and to my surprise there was a component on the
motherboard that was glowing red hot. I don't know what the component
is called, but here's a link to a picture of it, then a picture of the
motherboard to show reference as to where it is.
first I'd like to point out, part of my problem is likely dust and
dirt. but we'll get to that.

as I said, this component was glowing red hot. but! the computer turns
on just fine even now. it boots and everything.
aside from dust, what might have caused this, and should I be
concerned, once I clean it?
