Peter,

Gee your having a bad run ( happens to most of us )

APT is fairly stable and hasn’t caused any issues for me in 2 years using it

Windows can cause gremlins for sure

What version of Windows are you running ?

You may have had a “local brown out” in your area where the supply dropped a half cycle but didn’t cause a complete power failure ?

What type of 240V to 12v converter ? Some power supplies can cause glitches

I use Powertech 12v 7.5amp switchmode power supplies MP 3575 (3 off them to power my whole set up ) These have been very reliable for 5 years now

Power cables and connections check

Data cables and connections check

Check Memory and Storage on your Laptop on all drives

Maybe delete all your Astro apps and re install
Update Windows
Re install Ascom 6.6 and make sure you install the Microsoft.net framework 3.5.1 as well
Update all your drivers
Check Power Management in your laptop
Re install your apps
Try another run in APT

I’m no computer guru but I’d start from scratch and work through step by step

Hopefully others can chime in and offer more advice

Cheers
Martin
