Hi there,

A friend brought in his machine, an Asus P5GD1-VM with a 3.0 Ghz 775 P4 chip
with the fan hanging loose.

I put the fan back on, and the machine froze up real quick and then would
not even get video after heating up, more smell coming from the case.

I took the P4 chip out and put it in another MoBo and it worked fine, wow.

I took another Celeron chip and put it in the "burned" MoBo and same thing,
initial video, freeze, and nothing.

So, the MoBo is burned...... so if the fan fell away from the cpu, why
didn't that burn up and not work? Seems the cpu became so hot it burned the
MoBo??

Thanks,

Gordon

Video = thousand words
 
Perhaps the loose fan shorted something out. Who knows...

Weirder things have happened.

I use AMD processors, but imagine Intels are the same. They have overheat
protection so that if the cpu overheats, the computer shuts down. I doubt
very much the cpu would burn the mobo, but I guess anything is possible.
The fact the cpu works in another mobo suggests it is ok. It looks like
your mobo is screwed (to use a highly technical term). Fortunately, they
aren't too expensive to replace.

P4's have what is called thermal throttling circuitry in them. The processor
will save itself if it gets too hot.
 
But, obviously the P4 gets hot enough to burn the MoBo....at the same time
saving itself....saves my pal $$, too! As he just gotta replace the MoBo...
