I upgraded my CPU and now my computer won't work!

[windboit]

My old CPU, a ryzen 3 2200g is working perfectly, but I recently just tried swapping it with a ryzen 5 2600. When I swapped the CPU and the computer sees to be fine, all the fans are working and the lighting works, but my monitors stay black. I swapped it out with my old CPU, and the computer still worked, but the monitors were black. Everything was working well before I swapped the CPU out and none of the pins were bent. My motherboard is a Prime b450m, nothing is damaged so does anyone have any tips?

Do you have another gpu in it? If yes are you plugged into it, not the mobo?

If not, you need to get a dedicated gpu as the 2600 does not have an integrated gpu

Are you plugging your display into the motherboard's display-output? The Ryzen 5 2600 doesn't have a built-in GPU, so you can't use the motherboard-connectors for your display.

As everyone else has said, the 2600 doesn't have integrated graphics so you'll need a dedicated GPU. 

 

If you do have a dedicated GPU, idk what to tell you.

I have a dedicated gpu, Radeon rx 570

Clear CMOS and then boot with one RAM stick.

Did you forget to plug in the CPU PSU cables?

Clear the CMOS as already mentioned and then reseat everything.

Take everything out of the case and put the motherboard on top of the original box or on a wood or plastic test bench, away from liquids or random metal parts, assemble and hook everything up there, plug in the PSU, make sure all extra power connectors are plugged in, make very sure heatsinks are on, hook up your monitor and a keyboard and boot like that  (if you have an LED Post code, or or a "PC Speaker" attachment for POST beep sounds, you actually don't even need to hook up anything to the video card, not even any SATA drives or IDE/NVME ..BUT if you have a "PC Speaker" Beep speaker you can hook up to the main "SPEAKER" jump block to hear the power on "Beep" diagnostic, that helps even more.  The board -should- have a power button onboard.  If it's one of those super ultra cheap boards that don't, you will need to short the "PWR" case jumper block with a screwdriver.  Be very careful and make sure that screwdriver doesn't touch anything else.

 

With no drives, it should hang at the BIOS screen but will let you at least enter.  If that works then you have some sort of grounding case issue.

 

If that doesn't, then you probably destroyed something with static shock or knocked, scratched or did damage to something without realizing it.
