Computer doesn't start

[misiek4tt]

Hi,
I recently change CPU from i5 2300 to G840 because my last one broke.
When I start the computer, the fans work, the HDD works, GPU works and the processor heats up. I don't know what causes the problem?

Could it be that the pins are somehow bent and the computer doesn't start and just shows a black screen?

Also previously when I started up the computer I usually had a beep indicating that the computer is starting properly.
Please help.

Start by reseting CMOS.

Done that, now the CPU fans are spinning crazy fast, but still nothing happens.

Take out the CPU carefully get a decent light and magnifying glass and look at the pins, make sure they are uniform.
I had a problem and found some pins bent, used a small screwdriver bent them back and it worked fine!

Bent all pins back and it seems like the computer is working again, although I am getting a BSOD with Inaccessible_Boot_Device.
So I guess I'll have to get a clean W10 install.
