I'm working with a brand new PSU (Antec SmartPower 350w 24 pin) a brand new Ahtlon 64 x2 3800, and a brand new mobo (PC Chips A13G). I'm just trying to get a post and not having much luck. Right now I have 1 stick of ram in, the cpu and nothing else. No post. Have tried with no ram, still no post. Have tried all jumped settings, no post. Anyone have any ideas? This is my dad's system and I need to get it up and running asap. The only thing I did different with this is using an existing HD with an XP Pro install on it from a previous Mobo. I was assuming I could get to bios and do a clean install, but could have that messed anything up from the start?
