Bent CPU pins

[mushtar]

Hello. These days,I bent like 6 pins from my Ryzen 3 CPU. When I fixed roughtly,i put my CPU and cooler in my motherboard,which it caused my mobo could be supplied,but it didn't work.(maybe it's fried). Now the CPU and mobo are in a service but they can't do anything. The question is Can i test my cpu in a new mobo without risks? (if the service would have fixed the affected pins.)

My CPU was stuck in my heatsink and i used a screwdriver to remove from it.

i tell you a easy fix for this for your next time. run the pc. seriously let it run until its warm then you can remove it easily. or use hot air to warm it up carefully. works like a charm

Don't give those techs your CPU. Just get a pencil pen and align the pins yourself.

You still have to pay those guys if they mess it up or are unable to fix the CPU. And this isn't something a tech usually does, they most likely have zero experience with fixing pins.

When they will give my motherboard and CPU back,i will post some photos with affected CPU to tell me if the pins are now fixed enough.

You already gave them your CPU and mobo?

You will get it back when they have fixed or diagnosed the issue. It could be a few days or it could be a week. They probably repair other people's PCs aswell, you have to wait your turn.

Then explain why the motherboard is dead.

The service said that I didn't fix bent pins well and this caused this problem.

That is exactly what damaged the motherboard.

Sorry for the brief explanaiton as to why using another mobo would kill the motherboard if you alread tried to fix the pins yourself.
As Omega stated Ryzern and AM4 use a PGA configuration. PGA is where pins on the CPU connect to pads on the motheroard. Intel, since the Pentium 4 came out, has been using LGA...where in stead of pins on the CPU make contact on the motherboard...the motherboard has pins that make contact with pins on the CPU. The pins you see on an LGA intel CPU are there for the sole purpose of securing the CPU to the ZIFF socket. With Ryzen and AM4, the Ziff socket is set up in a way that it raises and lowers the pads from the motherboard to come in contact with the pins ont he ADM CPU. In that method, if the ZIFF connector is forced while the pins are in the wrong place, it breaks both the pin and the pad. Whereas in an intel LGA ZIFF slot (designated H3) you only end up breaking the arm that secures the CPU to the motherboard by trying to force it.

In short of the explanation...Because of the way LGA conects, having a bent or removed pin is fine so lonmg as you don't have the pad it secures in place damaged...you will have nothing but seating issues then...
PGA (which is what AMD uses) on the other hand, due to the way it contacts the board, is easier to break both.

The CPU is also dead. One more question: does the ram and gpu fried too?

The pins on the CPU are extremelly close together. There are over 1000 pins. Best procedure is to initially only handle the CPU by the edges. Never ever touch the pins directly. Position it over the socket and let it drop in to place make sure the CPU is flush on all sides with the socket . Don't apply any presure till you do. Then you can secure it in place with the lever. Once they are bent you are more than likely screwed.

I know. The CPU and MB are dead,but RAM sticks and GPU card?

[Viper]

It really matters which pins where in an issue actually. Becuase you most likely created some shorts but alll pins on the CPU do no access all parts of your PC.

How did you manage to remove the CPU with the heatsink attached? That suggests you fitted the heatsink without first securing the CPU with its bracket ... Either way, it's very hard to damage a motherboard via bent pins as they simply won't go in if they are bent so no real way to short it by forcing 2 into the same socket.

what happened to put you in a position to be removing the CPU without it being bolted down that lead to you using a screwdriver (!!!) To separate them away from the motherboard in the first place?

If you killed the motherboard and CPU did you have a power-spike or has your PSU died (you'll smell a burning smell most likely if it has from a dead capacitor), as that would be the most likely cause for multiple dead components, in which case ram and GPU could be dead also.

The service said that the motherboard is likely DEAD but the CPU is probably ALIVE,so testing my CPU in another mobo could affect the new motherboard?

They aren't OK testing it for you?

[Monk]

I fail to see how a CPU once they straighten the pins can possibly kill a motherboard, the only way I see it happening is if 2 are somehow forced into one hole and it causes a short, but no shop with the first idea about repairs should make such a mistake.

[Hare+Guu!]

There's no reason for a cpu to kill a mobo. The only feasible way, is to mount the heatsink in such a way that heat doesn't properly get dissipated through the heatsink and starts killing the socket itself. Even that is unlikely since it would turn off/throttle before it got hot enough.

OP most likely had a garbage psu, as usual. He probably broke some ground pins on the cpu or whatever, and the unstable psu got what it needed to kill off the rest of the system.

Now I never edited my own post but he's already said both parts are broken and as for why people have already said that the pins with the wrong shape destroy the socket.

They had no AM4 mobos for testing.

It wasn't forced. It fell very easy.

I tested my psu and it is alive.
