I found some clues.
In my hardware setup, my BIOS was very old, and some parameters was maybe wrong for Resolve so I flashed it to the most recent, making it fresh and back to base parameters.
Also I reactivated all Windows services (some of them where stopped to improve performance).
Note:
Because my PC isn't connected to the web, I don't have a firewall nor antivirus (a great solution to make the PC much faster).
After that, Fusion's viewers where working again, exept for some clips here and there.
So to my experience, when Resolve 17.2 and 16 got the same symptoms, it's probably not Resolve. It's maybe something "before" Resolve. So think the way the machine works: when you push the power button it's BIOS first, then OS.
My advice is to take the PC back to some "default state" before uninstall Resolve or anything:
1) Check BIOS. Boot the PC, enter BIOS, reverse all settings to default, test Resolve and maybe back to BIOS, adjust Disc, Bus, and GPU settings. Test Resolve every time you change ONE parameter. Sometimes one little thing make it working better or worse. Theses machines are sensitive like wild animals.
2) Check OS system. After boot, activate all Windows Services. Check Resolve. If it works, desactivate Services that you know don't have anything to do with graphics, audio and video (not easy, inside, Windows is a true mess).
3) Check Device manager to see if some hardware got a driver problem. If yes, update or reinstall drivers one by one.
4) Check the little non-Windows Programs installed if you have. Uninstall the one not necessary.
5) Refresh Windows with the install DVD
And finally, what I'm doing right these days (lucky me it's raining outside):
6) Make a clean install of the system from scratch, like a new machine.
Boot your machine with a bootable USB or DVD with Ubuntu on it (or other bootable system), it's free and got managing disc tools that can make the job done outside Windows, format the system drive, install a clean fresh Windows with latest updates and drivers. Let it do the job without finetuning anything, then resintall Resolve and test if it works.
If it is: great. Now backup!
With Windows Backup? NO! Make a disc image. Take the USB or DVD with Ubuntu on it, reboot your machine with it (so Windows IS NOT mounted), launch the disc manager, make an Image Disc and save it on another hardrive. THEN only you have a proper backup of all your system.
How many times the Windows backup isn't working well? So don't trust it, make a disc image OUTSIDE Windows. Never use the programs claiming to make a disc image inside Windows. Windows cannot backup itself totally while active. And when the Windows Backup system isn't working, it makes a corrupt backup.
Image disc outside Windows, the only solution. It always work perfectly for me and it was the only way to backup my OS through the years.
Note that if some hardware is faulty, a fresh system will not make it work better, so check first all devices.
