Changed CPU PC will not boot, black screen

Specs: Windows xp, intel p4
Hope someone can help? I wanted to upgrade my cpu from 1.6g to 2.2g. When I went to replace new cpu I dropped it and bent some pins, after some time I fixed that issue. Installed new 2.2 cpu and pc would not boot I mean nothing, just black screen and monitor in power save mode great! So, when I went to remove the heatsink to install the old cpu, the new one comes off with the heatsink, great! Installed old cpu and same problem black screen. Pulled the coms battery and set coms jumper to clear. Still have same problem. Did I destroy the mobo socket. Thanks for reading this.

looking at the psu u should be able to handle a pentium 4 we can cross the psu out of the list of problems
for now i CAN suggest that it is the socket pin in the motherboard u said earlier that u dropped some pins then fixed the problem then dropped the new heatsink!!?? to be sure if u can test the cpu on another motherboard if it works then we can guess that the motherboard is faulty

I doubt the board is bad unless you did something wrong during the CPU swap, like keeping the power cord plugged in. Assuming you didn't do that, the only other thing that may have gone wrong is the heatsink installation. The fact that the CPU ripped out of the socket when the heatsink was removed means that you either used the wrong type of thermal compound (adhesive instead of paste), or you used WAY too much paste. All that's needed is a tiny dab in the center of the CPU.

this is wrong!

this is right!

I'll clean it off and try again with just a dab?
