It started on changing the cpu, before I start changing the cpu, everything seems to fine and working, Then I accidentally fell the cpu into the socket pins, so the pin is pushed down, I managed to fix it, but all i see is the fan running without lights, sounds and display, then I switched it back to my new cpu after that when I started to run the pc, the fan run so fast and loud so I turned it off fast, I don't know what to do, I can't buy a new pc for now, Can I please ask for help. The bent pins is not broken.
