My Asus Tuf F15 FX506LH screen goes blank or shows whatever was there before me, and loud buzzing comes from my speakers. I tried everything: changing all programs and settings, even some that don't use ASUS software at all. Some of them didn't work well with the drivers. I tested different RAM and different SSDs too. I took it to a service center twice and they said there is no problem for sure. I ran many tests but the freeze happens randomly, never consistently in any test. What could be the issue here?

So far you've tried changing the OS or fixing the computer parts, so let's try stopping some of its sleep settings in your BIOS. Turn off CPU features like C1-E and turn off Intel's C1 power saving mode. Check what happens when you do this.

This version has few built-in settings, so those are just what I'm stuck with. I've tested them on and off without success.

Why are you turning off Hyper Threading? Look at each option and check for power-saving settings. Turn them off if they show up there.
