Recently I built aComputer using a 754 socket Sempron 2800+ with an ECS nForce3-A motherboard. Patriot RAM, Seagate HD, and FX5500 vid. and Antec 500w power. It runs great! Never one to leave things alone, I bought an Athlon 3500+ 64 and a used MSI K8N NEO Platinum mb. Also socket 754. Now when I start it, it runs for about five seconds and shuts down. I put every thing back the way it was before, except using the new processor. It runs great. Oh yeah, I'm using Win XP.
It seems to me that I bought a bad mb, but don't know for sure. Could I be doing something wrong with the MSI board? It came from Ebay so I know nothing of its history.
I didn't pay too much for it so I won't be out much money, but I've read that this board is really good if it works.
