Looks like your motherboard does not support WIndows 10. There are a lot of 1st Gen I5's with motherboards like you have that are working ok with Windows 10 but it seems yours is not. Last officially supported OS for your board was Windows 7, so it could be that something on your motherboard isn't 'updated' or 'controlled' correctly by Windows 10. This could also be the BIOS of your motherboard not being compatible, or "compatible enough". Did you upgrade from Windows 7? When you ran the upgrade advisor did everything check out ok?
The good news is that you say this problem started with the OS upgrade so that pretty much rules out everything but Windows 10. I see it's a gaming PC with your GTX970 so i'm guessing everything was fine under Windows 7. If you feel this is really the operating system one thing you can so is shoot an e-mail to Gigabyte and ask if this board can work correctly with Windows 10, and another is that you can revert back to Windows 7 if need be
