Those dell optiplex machines aren't made to be customized and when they are a series of problems could come up, I recommend talking to dell customer support

Perhaps you should try updating your BIOS. In order to do so, reinsert your elder CPU and download the latest BIOS from Dell. You can simply Google your Dell's model followed by "BIOS" and you should find your latest BIOS update on the Dell's site. I'd search for you, but you didn't provide the model number. Feel free to reply with your Dell Optiplex model number, and I'll search for you.

Once you download the BIOS update, it'll be an .exe file. Close all your programs, and run this .exe file. It'll update your BIOS and reboot. When you update your BIOS, you'll lose your configurations; so remember to set the "SATA Selection Mode" or similar back to AHCI (or IDE, whichever works for you) in BIOS.

Therein after updating your BIOS, you should be able to boot with your new CPU.

All the best. :)

If you mean won't boot by not going into the OS then you probably have to re install the OS from a image or save file or perhaps a clean install is needed. Do you mind clarifying what you mean by not booting?
