Broken pin on socket 1155 motherboard

I was installing a Noctua nh-d14 for my 2500k but upon booting back up, my computer would not get a video signal or show HDD usage. I don't think it is POSTing. I spent a good bit of time diagnosing things, when I decided to check out the CPU socket. To my horror, some pins were bent and out of shape. I did what I could to bend the affected pins back, but one of them looks like it is completely broken off.

Here is a picture, the red arrow points to the pin I am concerned about, as you can see it looks like it has been broken or bent in extremely. From looking at a pin diagram, I believe the pin is DMI TX [1].


I have no idea how this happened, but the only thing I can think of is that I tightened too hard on one side for the cooler. Is it possible this pin could prevent my computer from POST and boot up?

Sometimes you can get lucky and a broken pin is only a ground pin and not needed but most of those pins are needed, and you probably toasted your MB.

yeah, buy a new processor if you can find it. That one looks like it was handled by a four year old on a rampage.

The pins on 1155 are on the mobo, not the processor. The pins are naturally at an angle like that too, so most of the pins in that picture are actually fine.

From what I can find online, that pin is DMI_TX #1. That means it is part of the DMI (Direct Media Interface) or the bus that connects pretty much everything together. It may not cause a no POST but you will have random issues that may be intermittent or consistent.

Most likely you will probably need to get a new motherboard.

oh good point. *facepalm*

buy a new mobo. Those are probably easier to find than the processors now.
