I have an Asus A8S-X motherboard; it's a socket 939. I have an Opteron 148 cpu. My 6 year old used to use it and never had any problem with it. I upgraded him to a dual core Intel. So I took the older system and use it to play movies with my projector. But every time I turn the PC on, I get nothing on the screen, so I hit the restart button on the case. Then it boots normally, but at the beginning I get a message that says, "Overclocking has failed; defaults have been reset." But I'm not trying to overclock! I've never tried, and never changed any BIOS settings since my son stopped using it. I've looked, but don't see anything in the BIOS that would make it try to overclock. Anyone got any suggestions? It's just annoying to basically have to turn it on twice every time.
