Burning Smell !!

Athlon T-bird install, booted, and smelled burnt.
Shut it down, and pulled it. At the 6oclock position of the chip, there is what looks like a discoloration in the thermal grease--burn mark?--but every thing else looks normal.
I had the case off, and the fan spun up when I turned it on. I cant figure this one out.
ASUS A7V133 MB--default settings.

Can/Should I try this again?
Or it is Crispy, and if I boot again, I might fry the MB?
Thanks.
 
Chip is a goner. You probably had the heatsink installed in backward. See the groove on the bottom of the heatsink? That is suppose to line up with the raised part on the socket.

 
I had this happen to me with my Tbird. In an experiment, which I will skip, the heatsink ended up making poor contact. I did not realize what the cause of the smell was at first, but I recognized it as solder melting. ( I used to do a lot of soldering.) When I removed the heat sink, the the nice gooey white stuff I had just put on had become dry and a weird gray to black.
I fixed my problem, cleaned the gray gunk off with alcohol, reappplied HS compound and fired up the computer. The CPU has functioned perfectly ever since, although it was eventually demoted to a mobo downstairs. This CPU also has a chunk cracked off for another reason. Athlons will get d*mn hot without hurting them, although they say operating with no heat sink will kill them in seconds.

There are a few HS's with clamps that do not work by pressing directly on the HS at the center of the CPU slug. The old Golden Orb was one. They can sometimes make poor contact and actually be pressing just on one edge of the CPU slug, in which case their performance will be terrible
 
H/S is an Igloo by Glacialtech--- handles Tbird up to 1.4+. Mine is a gig'r. (Handles XP to 2000)
Hell, I am gonna try it again...

"Dude":
Hope you are wrong about the goner part. If you are correct, it was something else. Im positive the H/S wasnt backward.

My buddy from BestBuy thinks I may not have totally removed the plastic from the copper cpu shim, hence the nasty burning smell.

Excuse me while I whip this out...er,...rubbing alcohol that is.....Thanks all...let you know tomorrow.

 
When a coolant leak crossed on the Mosfets on my Epox 8K7A mobo I smelled it. Then it fried my Athlon XP with 2.5v to the core. All of the Mosfets got so hot that the board around them was delaminating from the heat... :disgust:
