I'm trying to get an older computer to work as a back up computer in the event my rig goes down. The MB is a Gigabyte GA-P43-ES3G it was really built for XP and Vista with WIN 7 support. It always has a hard time booting WIN10 but at one time I think it worked. Now no matter what (I won't bore you with all the details I've tried) it gets stuck halfway through the boot. Just won't boot, have to go into advanced troubleshoot etc. to get it to boot.
