We have an HP a6511a.uk desktop with Vista HP/32. As sure as can be that mobo has died - tried the usual steps (graphics card/psu/ram/remove all USB devices/memory card reader trick, etc) Problem with replacing the mobo with identical and addressing SLP issues? The actual model is m2n68-la narra3 rev 3.02 (partno 5189--1661 rev F01) as far as I can see the same mobo was used in Acer, Asus, as well as HP desktops. As I can't get into the BIOS, so would prefer the HP variety, but can't find any in the UK, so am wondering what issues I might find with using either the Asus or Acer mobo of the same model etc, or would I hit SLP issues? Anyone had expereince of this, or know how to resolve? Thanks in advance.
