========================

Detailed description:

On Windows 10, I'm getting a black screen when trying to wake the computer from sleep or o just waking the display (if computer sleep is disabled).

The computer freezes completely and the only way to get it back is to power it down and back up. Occasionally (rarely), the keyboard will be lit solid or blinking in this frozen state. Also, the power led blinks .

If I leave the computer frozen for a long time it heats up considerably, especially if plugged in.

This is a work computer so no games and no overclocking. BIOS settings are defaults (BIOS has been updated to the latest patch, 308) .

Computer has been cleanly reinstalled a number of times and is currently on Windows 10 2004 with the latest patches.


Troubleshooting actions tried:


BIOS update to 308 (latest available)

Disabling all possible devices one-by-one in Device Manager (Wifi, BT, card reader, fingerprint reader, display audio, system devices, etc.)

Tweaking power options such as disabling sleep, hibernation.

Tested RAM and SSD OK - even tried a different SSD at one point.

Installing driver versions downloaded from ASUS website (chipset, graphics and others) for this computer (VGA labelled Coffee Lake) and for a very similar model UX430UA (VGA labelled Kaby Lake).

Trying different versions of Intel Graphics driver (UHD Graphics 620) from Intel website, ranging from version 21 to the latest available.

I've wiped and re-installed Windows clean already 6 or 7 times, to different versions, but the issue happens starts happening after the Intel driver is installed by Windows update.

BIOS was reset to defaults.

The only way I've found around the problem is to disable or uninstall the Intel driver, but that leaves me without brightness control, etc.

Please help!

Thank you in advance.
