I came home from a three day trip and my PC turned off 1 second after starting.

 

After disconnecting everything, I reached 5 seconds.

 

Taking out the cmos battery for a few minutes and putting it back, I got a beep code: 3 long red, 2 short white. (Bad memory) No difference in other ram slots.

 

Replacing the ram stick with a new one reached 27 seconds.

 

Using both the new and old together stops turning off, but still doesn't output to any of my monitors.

 

Removing the cmos battery for a few minutes gets the same beep code with any combination of the new and old ram.

 

I cannot test the power supply directly, but the USB ports can still charge my phone just fine when the computer is off (better than my Nintendo Switch dock can.

 

I've only had this Z Workstation for about a year. I've never had a computer stop working this quickly. Any advice on getting it to function again quickly?
