I recently had the motherboard on a PowerEdge 2600 replaced.  Now when I start the system I get as far as the Windows Splash screen, after that I get a quick blue screen and the server reboots.  I have two HDs set up in a RAID1 configuration.  Using a utility I can see the partition and all the files on it.  It is set as active.  Any ideas on how to get the server to complete the boot up?  I know I'm probably missing something stupid.
