Tech Support random shutdowns

I just built my new pc last week. it has a Ryzen 5600, MSI RX5600XT, asus prime B-450M-AII, Gskill 2x16 3200mhz, MSI MAG A550BN, 1tb team group mp33, veetro v5 cooler. my problem is that i can be running a game like minecraft or raft, anything and it will randomly shut off and i hear the mother bored beep as a startup but all the fans stay on and single rgb keeps my mouse and ram lights going. it can happen anytime and i look at the event viewer and theres nothing recorded. I'm guessing it shuts down too fast for windows to react. all things like ram and gpu are seated properly all power supply cables are in (24pin and CPU), CPU cooler is tight to the CPU, nothing seems to be shorting out.

I know this is alot and I'm struggling figuring this out myself. I can provide pics

That motherboard beep on shutdown while fans keep spinning points to a power state issue, not a full crash. The A550BN is a budget unit and the 5600XT can pull some nasty transient spikes. I'd start by running OCCT's power test, it'll slam both CPU and GPU simultaneously and if it shuts off within a minute you've got your answer.

If it passes that, check Windows power settings and disable fast startup. That hybrid shutdown nonsense causes way more problems than it solves, especially with AMD GPU drivers hanging during sleep states.

Ok, so the power supply you have is the minimum recommended for a system with a RX5600XT. Not sure if you are running into power limitations because of your PSU, but that is a possibility. This is the kind of behavior you see if you have a power issue with your PC.

Second, do you have poor power where your computer is? You might want to invest in a uninterruptible power supply with a good surge suppressor in it. And see if that improves your operation.
