Did my CPU just die on me?

[DriedSponge]

Hi there,

I was playing Apex Legends today, and then all of the sudden my monitors went black and my audio completely cut out. I checked on my PC and everything looked physically fine. Everything was still powered, including the GPU. I tried rebooting my PC but now I am just presented with a red CPU light on my MSI motherboard. Are there any trouble shooting tips people would recommend to maybe fix this?

Here is what I've tried so far:
- Restarting my pc
- Unplugging the PSU and plugging it back in
- Removing the CMOS battery and putting it back in

I have yet to try to re-seat the cpu because I do not have enough time (my AIO is incredibly annoying to take off my cpu), so I will try that tomorrow. I will also re-apply the thermal paste just in case.

If my CPU is dead, it would be incredibly annoying because I just got my PC up and running again after going through a 3 week RMA process with Arctic to get a replacement AIO (the new AIO they sent me does work).

The CPU I have is a Ryzen 5950x and I'm running on a MSI B450 Tommahawk. I would like to mention that things were running just fine months ago, and even for a several days after I installed the replacement AIO from Arctic.

If you have any questions for me please let me know, and thanks in advance for your help!
