A Dell PC has recently started taking from 30-45 minutes to boot up into the login screen.
From there, it functions normally.
The Event Viewer shows nothing unusual, and there are no bad devices in Device Manager.
What else should I be looking at?
It is hanging on a simple black screen, before the BIOS self test. It is a member of a domain. I can't see anything referencing this computer in the event log of the domain controller, but I'm not sure what I should be looking for.
