AMD Cpu Issue

Alright, I'm faced with somewhat of an odd issue with an AMD Athlon X2 5600 cpu.

The pens were pent on this cpu, and finally were straightened out so it fits into the socket. I put it in the socket, and installed the heatsink. When I started up the computer, it would beep..not boot up...obvious CPU issue.

So I had been trying to figure out what the problem was, and instead of reseating the heatsink and clamping it down every time I tested it, I decided to just set the heatsink on the CPU without locking the heatsink down. This time, it worked great and loaded up Windows Vista fine.

BUT when I clamp down the heatsink, the motherboard never fails to give me the CPU beep error and doesn't boot...so I'm not sure what I should do to get past this? Has anyone else experienced something like this?
 
Well, I have tried that. The CPU works when it is in the socket, with the heatsink just "laying" on it, but when I fasten the heatsink down, I guess the additional pressure on the CPU is what is causing it not to run? I'm not sure why? But it is functional, just not when it is securely fastened to the mobo.
 
Thats strange because putting on the heatsink would make it press in further. No pins are broken off are they?

You really have to make sure all the pins are perfectly straight again. Do you have another CPU to test and make sure the mobo socket wasn't damaged in any way?
 
Yes. I have a AMD 4400 CPU that works fine in the same motherboard, with the heatsink properly installed.

This CPU works fine, it's just, as I mentioned, when I clamp the heatsink down...I guess it applies more pressure on the CPU and then it doesn't work.

When you don't clamp the heatsink down, and just let it sit on top of the CPU loose so it can stay cool it works fine. I booted into Windows Vista and ran some CPU intensive programs with no problems. I even tried to clamp the heatsink down AFTER the CPU was already running, which froze the computer. After unclamping the heatsink it worked again just fine.

So I'm at a loss of what to do. :( Any more suggestions? I can't recall the pins that were bent on the CPU since they all appear very straight...there is no thermal compound on the CPU's pin surface or on the pins. Maybe there is a way to secure the heatsink to the motherboard without appling as much pressure to the CPU, as the normal clamp does.
 
Must have cracked a transistor or something inside the CPU, when pressure is applied it shorts or something. Just something wild to throw out there as an explanation. Either way, I would stick the 4400 in and get a newer CPU. Does your board support AM3 CPU's and/or Phenom II's? What board do you have?
