Are you referring to the time it takes to start booting or the time it takes to get to a Windows logon prompt?
A long delay in booting can be a bad power supply or bad hard disk.
A long delay waiting for Windows can be a bad hard disk, virus, or corrupted Windows install.
You'll need to be a lot more specific about your issue.
