So I changed out the case of my girlfriends computer. I moved everything over but when I went to change the thermal paste out. The Cpu came out with the heatsink. I took it off carefully and cleaned the thermal paste off. Went to replace the cpu to the socket after fixing the bent pins. The cpu went in fine but I notice to set the retention arm down there is almost 0 force needed. Also the cpu is movable. It's an AMD Athlon II I believe. I got it in and installed the heatsink and turned it on. Everything works.. but no display. So I took it apart once more and the cpu again came off with the heatsink. Fixed the pins again and reinstalled it and still no force on the retention arm. Gpu's working fine.. So not sure what I can do to fix it.
 
Replace the motherboard, or the retention hardware.

If you had to straighten pins, especially multiple times, then it is VERY possible that the pin's solder point INSIDE the CPU is broken, hence the failure to display. It's also equally possible that some pins are not making good contact since the retention lever tend to create that contact between the pins and the contacts by applying pressure to the top of the CPU. If you can move the CPU once it is installed, then there is a problem.

I'm not able to move the CPU once it's installed. Is there anyway I can fix it?
 
Removing the heatsink from CPU requires gently twisting in a clockwise and counterclockwise motion until the heatsink becomes free.

Pulling the CPU out of the socket can damage the CPU and the socket. Replacing the socket I believe costs $80-$100. It may be more economical to replace the motherboard.
 
It makes a lot more sense, to replace the motherboard, IF the motherboard is damaged, and IF you can't source a replacement mechanism for cheap. Also, if the CPU is not also damaged, which there's a good chance it could be after pulling it out multiple times in a way that it was not meant to be removed.

Bending pins more than once usually results in broken pins. If any pins feel "loose" then it's done.
