Slow boot, services failed

I'm working on a server running Windows Server 2003, 4 days ago we had a power outage and when the server booted back uo it took forever to get into Windows, it would not see the network, and there are no network connections showing, tryed to start services but keep getting error message. also on boot up, as it is preparing network connections, I get a message about driver or service failed to load.
Help Please.
