Dell PowerEdge T410. 2 drives mirrored. Server 2008 Standard-up to date
It gets to the splash screen, then as it goes to the next screen it goes to a dark grey background and my mouse pointer is showing and that's it. It will stay there for an hour. I should be seeing the loading system services, applying policies etc. screen and then ctrl-alt-del.
With both drives connected via RAID controller: -Can always start in safe mode -Will only start in normal if I randomly disable a service or 2
With one drive connected as degraded RAID (for fun I unattached one drive and everything works) -Always starts in safe mode -Always start in normal mode
Tried 2 new hard drives, controller card, cables, updated BIOS, drivers, controller BIOS, drivers etc. Tried system repair.
In a nutshell, with both drives attached I boot into safe mode to troubleshoot, nothing in the event logs, I disable all startup items and non-microsoft services.
System will reboot fine a couple of times. I go back into safe mode, enable a service, system will not boot. Go back and disable this service, system will still not boot. Try another service, then it will boot, back to square one.
So after a number of tries, enabling and disabling services will sometimes help and sometimes not. Very weird.
