Enabling AHCI in BIOS

Should I switch SATA HDD mode from IDE to AHCI, when installing Windows 10 on a computer that doesn't have dedicated drivers for versions beyond Windows 7?

Will leaving it on IDE minimize possible incompatibilities due to a lack of SATA AHCI controller driver?

If you are switching from IDE to AHCI, then switching before installing Windows 10 is the best time to do it.
Windows will provide the drivers during setup. So allow Windows to finish setup, which will continue until Windows update kicks in and finish download necessary drivers.

You don't need your own AHCI drivers unless your chipset is doing something out of the ordinary like RAID.

Even Windows 7 handled AHCI just fine, but if it was installed when the SATA controller was in IDE mode, Windows didn't tell the drivers to load and switching the SATA controller to AHCI mode later became problematic but not impossible.

Unless you have a good reason, I wouldn't throw away the free performance you get from running your SATA ports in AHCI mode.

Just have your SATA ports running in AHCI mode when you install Windows 10.

The reason why I asked this is the first place is because I've already tried switching to AHCI while I was upgrading my old PC and when it booted up everything seemed fine. Unfortunately when I put the PC to sleep and then tried to wake it up, it completely froze. Switching back ti IDE fixed this problem for me. Now, I'm assuming this was an isolated incident, but it still bothered me a little when I had to install Windows 10 on other older models...

Not having the appropriate drivers seems to cause problems in certain cases.

Sleeping and waking a PC has never been a guaranteed affair. Some hardware just doesn't work correctly after the computer is put into and resumed from a sleep state. May be an issue with the firmware on the drive. Could even be an issue with RAM stability, as sleep requires RAM to be powered and it's contents retaining sometimes for extended periods.
