The Display driver is so important here that merely updating it is sometimes not enough. So let's try everything possible to get it working correctly:

First make sure you have updated the Display driver from the PC or Display adapter maker's Support Downloads web page for your exact model number, HP Serial Number or Dell Service Tag - from the sticker on the PC.

While there check also for newer chipset, BIOS/UEFI firmware (very important), network, sound, USB3 and other drivers, comparing to the ones presently installed in Device Manager reached by right clicking the Start Menu.

If necessary first remove the old driver using DDU https://www.wagnardsoft.com/content/ddu-guide-t... (not necessary with Microsoft Basic driver which is a placeholder if nothing else is available) and/or installing in Safe Mode with Networking (so you have internet), or Safe Mode, accessed by one of these methods: https://www.digitalcitizen.life/4-ways-boot-saf...

If new driver still won't install DDU see Lightning Leon's Answer here: https://answers.microsoft.com/en-US/subject/for...

If this doesn't give you the latest or ideal driver for what you need, compare it to the driver offered by the Intel driver update Utility here: http://www.intel.com/content/www/us/en/support/...

or the Nvidia GeForce scanner here: https://www.nvidia.com/tr-tr/geforce/geforce-ex...

or the AMD autodect utility here: http://support.amd.com/us/gpudownload/windows/P...

For Display issues one fix that is working is to Roll back or Uninstall the Driver on the Display Device > Driver tab, restart PC to reinstall driver.

You can also try older drivers in Device Manager > Display device > Driver tab > Update Driver > Browse > Let Me Pick.

Then you will know you've tried everything in addition to Windows Update drivers.

Adjust the screen resolution until it fits and looks best at Settings > System > Display.

Feel free to ask back any questions. Please report back results for all steps given so I know what else to suggest if necessary.

I've had the pc for 2 years and it just randomly went black. I later lowered the refresh rate and realised that's what was causing it . Also I've done this with 2 different monitors

Hi, I'm Elise, and I'd be happy to help with your issue.

If the screen is going black when you increase the refresh rate, it is likely that the combination of resolution and refresh rate you have set on your PC is not support by the monitor. I would consult with the monitor manufacturer to see what modes are available to you.

Please let me know if you need any further assistance.

Kind Regards,

Elise

In that case it sounds like the display driver, I understand you have said you uninstalled and reinstalled. Can you check with the PC manufacturer if they have a newer version of drivers to download?

Kind Regards,

Elise

I checked on the website and downloaded the latest drivers
