Is My Cpu Burnt?

Specs: Windows XP, amd athlon 64 x2
Ok so i was on my computer and all of a sudden the screen got distorted so i turned it off. when i turned it back on nothing came on the monitor except the red blue green box thing. so i assumed it was the video cable or monitor but i hook them up to a older computer i have and they worked fine. next i checked the cpu and it had some grey chalk on the back so im a bit concerned. somebody help?

Modern CPUs have built-in thermal protection circuitry, it's almost impossible to overheat one to death. I'm not 100% sure what you mean by "grey chalk" but if it was between the CPU & heatsink, it was a thermal pad. You need to thoroughly clean the top of the CPU & bottom of heatsink of all traces of the old pad, then apply a small dab of thermal paste using the "middle dot" method. Do not attempt to run the system without thermal paste. Here's the instructions.

When you attempt to restart, do you hear any beeps?

A CPU will NOT work with bent pins. If any of the pins are bent, it's because YOU bent them. The CPU socket is called ZIF socket, ZIF = "zero insertion force". If you had to put any pressure on the CPU to try to get it back into the socket, you probably had it turned the wrong way. 3 out of 4 possibilities are wrong, only one is right. Sounds like you effed up.

Many consider a 'bent pin' the end of the socket/motherboard. That depends upon how careful you are and how much patience you have. I do not know the AMD sockets, but I had a P4 socket 478 (straight pins on the CPU) and one of those pins straightened fairly easily with a fine smooth needle nose pliers (purchased CPU used). About 6 months later I had a motherboard (also purchased used) with a socket 775 that may be similar to yours, that was much more difficult. I made a tool by gluing a medium sized pin point into a small dowel and cutting off part of the eye (using dremel tool) leaving a tiny two prong fork. Using this tool and a 10x jewelers magnifier, I reestablished the proper elevation, angle and alignment to the same as all of the other contacts to within 99.99% in about 45 minutes. If you can do it, it is very slow delicate work. Most cannot.

You have to be a little bit crazy to keep you from going insane.
