CPU Pin bent ? - Page 2

post #11 of 18
Thread Starter 
Here are some pics, maybe this will be clear enough what I mean :

Attachment 213817

It's the one in the top corner, I pointed it with the red arrow.

You notice that pin being a bit shorter ? (the tip is gone)

Attachment 213818

And it being dark colored, like it had shorted out or something ?

I can't get it any higher without breaking it...

Any thoughts ?

It almost looks like the gold plating has failed / come off.

You could look up the specs about what pin does what for that CPU socket.

EDIT 2: It looks like that pin might not actually be used.

The thing is, a couple days ago my psu stopped working. I had issues with it for quite some time, that is, when cold booting it would never boot the first time. I always had to turn the pc off and on again, and then it would boot. This went on for about a year, and couple days ago it went dead.
I tested the psu on another rig, so I'm sure the psu is broken.
This was with my asus mobo which has the bent pin.

I hooked up a new psu and mobo yesterday, and only now I'm noticing this on my asus.

I thought my psu just went dead, but now I'm beginning to have serious doubts that it was in fact this fried pin that eventually killed my psu.

Strange, because the cpu itself is still alive and kicking in my new mobo (gigabyte).

Could it really be this pin that killed my psu over time ?

Hey, man, awesome thinking !
But which quadrant is the pin in ? I'm not sure but I think it is the lower left quadrant (figure 8-3) and the pin is CGC_TP_NCTF, which is not in the list of unused pins ?
Could you help me out here to locate the right pin ? And thanks a million for this, dude. Would never 've thought of this...

Ok, I found it. It's in the lower left quadrant, pin B39 (CGC_TP_NCTF).

Attachment 213822

In the list of pins, it shows up blanc. Does that mean it isn't being used ?

Attachment 213823

But could someone explain, if it is not used, then how can it get damaged like this ? I mean how can it be burnt if it isn't used ?

So probably there was some kind of short out (most likely caused by my defective psu), but thanks to this ground point protected the cpu. And that's why it looks burnt. Am I right ?
