Windows 10 Doesn't Work on Older Motherboards?

[Rezident]

I was going to try W10 but it looks like it doesn't work on my motherboard: Asus P8Z68-V. No motherboard/chipset drivers for it on ASUS site and it's not on the Asus list of W10 boards:

Wow, I honestly never thought that would be the problem with W10! So is that it then? Windows 10 doesn't work on older mobos? Why not?

I have the P8Z68-PRO and it works OK with drivers installed automatically.

I do have intermittent issues though, may be something misconfigured my end but I'm fairly certain it's related to Windows 10s power saving / fast start-up modes. Never had these issues in 7 or 8. USB ports intermittently don't work on boot, requiring you to disable and then re-enable the port through Device Manager... bit of a pain if its the keyboard or mouse that's decided not to work! Also sometimes it just fails to start-up, it sits on a black screen for a few minutes before rebooting and then starting OK. The event logs show an unspecified failure of fast start-up when this happens.

Are there still all these bugs with W10? I thought it would be pretty much fixed by now, that's why I left it til now to up?grade.
