Windows 10: how can I fix screen distortion?

Repeat of problem. I had my PC serviced recently and a problem with screen distortion has recurred.

:)

 

Screen size does not fix.

Since the new upgrades the screen size is too big for my 7 YR old Toshiba Laptop, which I use constantly. I Can not access the x or the scroll bar. The character's are Hugh, stretched and distorted. I have followed every single step listed in troubleshooting
and even paid two computer techs to fix it. NOTHING WORKS! There used to be a simple one step adjustment: Settings: Display: Screen Size. Neither, Resetting, troubleshooting app, driver updates, changing to another resolution (which btw is suggested as a
fix but non existant) nothing works. I am at wits end. The last guy I paid to fix it suggested I just buy anew unit? I can't afford that. Please please address this issue asap. Thank you

 

sound distorted after windows 10 anniversary upgrade

This is where I'm at on my HP laptop with Windows 10 and the Anniversary update.

I completed step #3 "hardware and sound" but that took me to an option for "sound, speakers." There was no "properties" as step #4 suggests. I selected "sound, speakers" and then found "properties." After selecting "properties" there was no "enhancements
tab" as step #5 suggests.

Regardless, I then uninstalled the realtek audio driver. I noticed that when I did this without restarting my laptop that the sound was now tinny, but not distorted as it was previously. After restarting, the sound was again full, yet distorted.

Realtek still shows in my programs list, though it shows no memory is used.

Thanks for your continued help.
