A couple of methods. Shutdown Router then same to computer. Disconnect all external drives. Restart Router and connect computer via Ethernet Cable ( Wifi is iffy ) Restart computer in Safe Mode ( Shift ) - immediately at startup. It does Repair Disk, Clears cache and only loads Apple Software and Fonts. Load slowly - normal. Try again and if possible do not let computer to go into Sleep or Screen Saver mode.
If over Wifi - same as earlier except Disconnect All Other devices using the wifi - what the Max Bandwidth for this computer.

Go have a coffee, or lunch, and give it time. As they say, a watched pot never boils...
was leaving it to run overnight for the last try long enough?
You said 15 minutes. Now you say overnight. Of course if it is not able to complete overnight that is a problem.
Try P. Philips's suggestions.
