I'm currently switching from an i3-6100 to a i3-9100f. I put in the 9100 and proceeded to turn on the pc and it started for 5 seconds and turned off. I looked into the problem and it said I needed to clear the cmos which I did and I still had the same problem. So the other option was to update the bios by putting back in the i36100 which I have now done and the computer powers on fine the fans spin on gpu and cpu but now the monitor is saying no display detected I have tried plugging in the hdmi to the motherboard and that also didn't work. Also tried re stating the GPU. I dont know what to do at this point and any help is appreciated.
