My mini laptop starting freezing recently to the point of being unusable. Seems an update to the AMD graphics driver has caused the issue and i’ve managed to fix it using the guide below – thanks to user LutherGaylord

The problem is the new AMD graphics driver, which gets installed automatically by Windows Update.

It is not compatible with Windows 10 on this laptop; it makes the computer utterly unusable.

But there is a solution:

(1) Tell Windows to stop installing hardware drivers along with updates.

Control Panel —> System and Security —> System —> Advanced System Settings —> Hardware —> Device Installation Settings

“Do you want to automatically download manufacturers’ apps and custom icons available for your devices?”

Select “No” and then click “Save Changes”.

DO NOT SKIP THIS STEP, or Windows will re-install the rogue graphics driver after every reboot.

(2) Uninstall the current graphics driver.

Device Manager —> Display adapters —> AMD Radeon HD 8250 —> Properties —> Driver —> Uninstall

(3) Install AMD graphics driver 15.200.1060.0 (17 Aug 2015)
