No boot after cpu upgrade
Dell Inspiron 3670 manufactured 3/2019 BIOS 1.5.9
I tried to install a brand new boxed 9th generation I7 9700 and the computer won't POST. I tried reseating the CPU but still no POST.
I reinstalled the i3 8100 it came with and it boots normally.
Would a BIOS update to the latest version solve this problem or is there another issue I need to address.
Thanks for any and all help.

The specs say this PC supports 9th Gen CPUs, so -in theory- even an older BIOS should be OK.
If you want to update BIOS, you'll have to do it with the old/working CPU installed. Then unplug PC and swap in the new one. Next, reset BIOS by removing the motherboard battery and pressing/holding the power button for ~30 sec before reinstalling the battery (time for a fresh battery?) to make sure BIOS sees the CPU change.

Looks like it was just a BIOS issue. I did a BIOS update to the newest version and then installed the CPU and that fixed the issue. The computer boots fine on the new CPU. Combined with the M.2 drive I installed, the i7 9700 makes the system SUPER FAST. The time for pressing the power button to being logged into Windows 10 is aroundc18 seconds!
