Hi... A friend of mine has a MSI K9N SLI-2F, nForce 570 SLI mother board. Lately it's been acting up. The pc won't start up and he has to restart it numerous times before it finally starts up. Once up and running it suddenly freezes and he has to do a new restart again. I tried to help him by inserting the os cd (win xp) and see if it could be a os error, but the dvd rom won't read the cd. Black screen with a error saying "Reboot and Select proper Boot device or Insert Boot Media in" is all that pops up. The bios recognizes all components including the dvd rom. I set it to first boot device but still nothing:-( I tried other cables etc. to eliminate faulty wires but no... So my questions are: Anybody got any idea of what this could be? And..does anyone know where i can get my hands on a manual for how to set up the components (thought i'd disconnect everything i start from scratch)?
