[SOLVED] Monitor, keyboard, and mouse suddenly stopped working ?

[Vxizon]

So what happened was I was watching clips with my software then suddenly my monitor blacked out as well as my mouse and CPU, and the CPU light is on. I tried getting new thing a new CPU and power supply and trying to move around the ram and tried upgrading BIOS as well and taking out the motherboard's battery as well.

my parts are
CPU amd ryzen 5 3600x
GPU msi Radeon rx580
Case montech x1
Motherboard msi b550 gaming plus
Power supply thermal take smart 700w
Ram Corsair 2 x 16 ddr4 vengeance pro rgb

Power supply thermal take smart 700w
That is the first thing that stuck out as the problem. You should be on a reliably built PSU.

See if borrowing a PSU from a friend or neighbor who owns a reliably built PSU with at least 650W of power for the entire system changes your experience.

How did you upgrade the BIOS on the motherboard? New PSU as in, the same unit you own but brand new from the store? Link to your ram kit and the slots you were using the rams on?
