Hey, your HP Pavillon motherboard seems to be in good shape based on your last experience. Since you didn’t touch it and it worked then, it’s likely still functional. The fact that it powers up with the PSU connected but not everything suggests there might be an issue with the power delivery or a loose connection somewhere. Trying to connect components one by one could help identify the problem. Just be careful when handling it—don’t short-circuit anything.
It's pretty odd it features a 4-pin instead of the usual 24-pin. The front IO is linked and looks like a laptop connector, labeled "PRWCMD" on the PSU. The name is "ERICA_ERICA2"—HP seems really excited about their new boards!
They were still reasonable for a while. I see you’ve returned to normal. You can create a board that meets ATX requirements or simply skip it. This seems like a case where ignoring it might work. The setup should function well with the correct components, which are likely exclusive to the maker. The “Erica/erica2” model can be researched online for more details about the system if needed.
Yes, the power headers on a motherboard function even without a CPU or RAM.
