Did I just get a bad CPU?

Hello All!

I am having a problem with a recent build and am beginning to wonder if I simply have a bad processor.

I recently bought a MSI B550 Tomahawk motherboard and an AMD Ryzen 5 5600 G processor to go with it. (Both at Microcenter of course)

I set up the build and connected power. While all the fans went on and spun, etc., no video signal was received by the monitor. Cpu light glowing red on the troubleshooter built into the motherboard.

I plugged my old processor an AMD 7 1700 X in the same setup and got to the BIOS/setup screen right away, using an Asus rx 550 4G video card.

Fearing that the BIOS needed updating, I went to the website, downloaded and installed the latest BIOS update, and successfully flashed the BIOS (Version 7C91vA92)

I put the old processor (Ryzen 7 1700 X) back in, along with the aforementioned video card and booted to the BIOS screen, no problem at all (even seemed a little snappier, but that could have been my imagination).

I put in the new processor (the aforementioned AMD Ryzen 5 5600 G) and hit the power button. Same result, fans spin, no video signal at all. (Red CPU light on steady red on the motherboard)

I pull the video card and plug the HDMI cable directly into the HDMI slot on the motherboard, thinking that perhaps the video signal is being diverted there due to some innate software or jumper setting, and try again. Same result, fans spin, no video signal.(Red CPU light on steady red on the motherboard)

Is there something obvious I am missing? Do I prob. have a bad CPU? Any and all thoughts and observations welcome and thanks in advance!

Greetings. If the BIOS is showing the updated version, you can try re-seating and ensuring cables are still secured after the CPU swap, but based on what you are describing, it sounds like it very well could be a faulty processor.

I hate to say that, but yeah. MSI tech support via email was no help whatsoever.

Does anyone know if MicroCenter will test the processor for me for free if I drive there (since I bought it there)?

Ian

Greetings. We would not have a free testing service available. The only diagnostics we offer is on full builds, not individual parts, and that service would start at $39.99.

I think your best course of action would be to attempt an RMA. Since the motherboard works with the older processor on the new BIOS it must be a faulty 5600G

Red CPU light on steady is the key; that means your motherboard is convinced the CPU has a problem.
