I have a SAPPHIRE PI-AM2RS780G AM2+/AM2 AMD 780G Micro
ATX AMD Motherboard. I was getting a post error 25. The problem ended up being my
PSU. Once I changed that, worked.
Sorry, I know this post is really old but it was never resolved.
EDIT: Just wanted to recreate the error, so I pluggin my old
PSU in again and this time it worked. Not sure why. Maybe the connection wasn't tight the first time or something.
Well, in any case, it's something to check.
EDIT2: Okay, it's doing it again. It was fine for a while. Then I put a Fedora CD into the tray and rebooted. Nothing. This mobo is crappola.
