OP, QWuan (hp facts I know and examples) HP owns Compaq, for 17 years today. so HP supports all Compaq now and for 17 years. HP has your manual, but can be hard to find over 10 years. HP deletes support on some at the 10 year mark, (not on enterprise grade PCs etc) go to hp.com or google. here 1st hit on google goes right to it, amazing no? the google bot knows where it is. amazing.. true.
best I can tell 10 years old today this old desktop what do you need to know HP does not document fully motherboards. in many cases. what is wrong or what are you attempting giving clues like that makes help 10x more easy. did you buy a full PC case and all or just some old used mobo off fleabay? hints are welcome here. tell what you are attempting,? please.
in some cases (no pun) the mother boards used are from ASUS.com maker, under contract to HP. if yes, we can in fact get vastly better documents on any ASUS, made. or others, as your seems... one Compaq SR-55xx uses MCP61Pm motherboard, unstated by you btw. and at hp you can search that too. example, of above, MCP61 https://support.hp.com/us-en/document/c00906137
