1) Reseat all your RAM. Take it out, swap the RAM sticks if you have multiple, put them back in firmly. Check status
2) Remove your graphics card and test. If you're on Ryzen, then don't bother. Check status
3) Unplug all unnecessary things. Any extra drives, any extra connectors, just a monitor, keyboard, and mouse. And also power. That's sorta necessary. Check status
I've had multiple friends have random issues like this and sometimes reseating RAM worked, sometimes unplugging specific drives/accessories worked, and sometimes the GPU also needed to be reseated.
Computers are weird.
(Also what motherboard do you have?)
