Smoking CPU :( ?

Fired up a PC I was given, heard intermittent crackling and smoke come out from under my H60i. Turned off my PC at the wall. I took it apart and it all looked fine, so put it back together again but unsurprisingly it won't fire up.

The green light on my motherboard works, so I assume my motherboard might have got away with it. When I press the power button, the fans will start spinning (and I hear the H60 pump do something).

Is my CPU dead? Motherboard dead? Powersupply CPU cable dead?

magic smoke=death in all electrical components i'm afraid. :(
 
+1 for dead cpu

(btw you dont know anyone from fort william, Scotland nearby you?....into his mountain biking......my bro :) )

Did you actually see smoke come from the CPU? if you did then it's dead, if not it may be something else.
 
Smoke seemed to puff out from under the left side of the h60 pump but the pump itself seems fine. The pump is quite big so I guess the smoke could have been coming from the motherboard but there aren't any components that close to the socket.
 
Only thing to suggest is possibly try other components.

First, try a different psu in your system. Then if you can swap out the CPU and try in another working setup. This is the only way you'll be able to narrow down and confirm I'm afraid.

i'd hazard a guess that its a component near to the cpu that has gone. If there was smoke then you should see visible damage somewhere. Take a look at all the chips surrounding the CPU and see if you find something.
 
Well I got a cpu from DK4J (or something like that) and it still doesn't work so sadly I think you're all right and it's the motherboard. Maybe the original CPU survived?

There isn't any visible damage on anything.

Oh yeah and I tried another PSU, same result.
 
If your CPU is smoking then the only cure is to give it some silicon patches but the cravings can get bad !!!


Ok jokes aside smoke usually means something is dead in your system, Try and test parts 1 by one if possible and as you said it was the mobo be super careful when testing parts in a new mobo.
 
Left side of pump (if by that you mean left side of socket with board stood up like normal in a tower case) is probably vrm's.

New mainboard seems in order but might be worth looking at PSU as well, could be running one of the rails far enough out of spec that it's eventually killed one of the VRM's. Take a look when you take it out, check the underside of the board, check there's no odd screws or anything silly in that kinda are and that there's no standoff where it shouldn't be on the plate the mainboards mounted on.

Unlucky but at least you have an excuse for an upgrade now :p

H61 board and a pentium "Gxxx" would be about the same as you have now (1155 - sandy/ivy bridge) and give you upgrade options or stretch to an I3/I5 if money permits maybe. Possibly even head towards Haswell/s1150 based if you want shiney and new.

Just to add, I would not be powering up the system again with a dead CPU/motherbiard as you do not know what will decide to join it as well. If you cannot see physical damage on any side of the PCB around the CPU socket, I guess it's not the motherboard. Do not plug a fit CPU inside before you are sure there is not visual damage on the motherboard as it might have died, taken the CPU with it, and take the other one victim as well.
