ENVY 27" All-in-One b214 Intermittent Flickering Lines on Screen

[YALE70]

Hey guys,

We've had this ENVY 27" AiO since November of last year with no issues to report until this past week when the screen just randomly starts going haywire. It seems to occur some time after log-in and lasts anywhere from a few seconds to several minutes before stopping, afterwards everything seems normal. This seems to occur about once a day and I've tried installing this firmware patch from HP(https://support.hp.com/us-en/document/c05939024/) though I'm not even sure it installed properly since the ISPTool executable closes immediately after it opens(not sure if that's normal behavior). I have also tried disabling the onboard Intel UHD Graphics 630 via Device Manager but that doesn't appear to done anything either. I'm under the impression this might have been caused as the result of a botched update at some point but I can't be certain. It seems fairly difficult to find similar cases for this particular machine.

Specs:

OS: Windows 10 Home (Version 2004)

CPU: i7-8700T

RAM: 16 GB

GPU: Intel UHD Graphics 630 & GeForce GTX 1050

Storage: 256 GB M.2 SSD & 2 TB HDD

Any help will be greatly appreciated. Thanks!

I reviewed your post and I understand that you are facing issues with the display on your computer.

Don’t worry, I assure you I will try my best to get this sorted.

What is the version of Windows installed on your computer? (Like 1903 1909 or 2004)

Meanwhile, I recommend you update the BIOS and the graphics driver from the below link and check whether the issue is resolved.

Let me know how it goes and you have a great day!

It's running version 2004.

I'll report back if the driver and BIOS updates work. Might be a moment since I have no idea when the flickering lines will appear again.

I updated the BIOS and the drivers for both display adapters/graphics cards per suggestion but the issue is still occurring. Again, this was not an issue prior and I almost feel like the latest Windows update(or some other update prior) is the cause of this problem but I'm not sure how to diagnose it. 

Would you also be willing to specify which exact drivers I need to install and the process of doing so? There are several drivers for both GPUs. I installed the latest available for both.

Thank you for posting back.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Firstly, perform Windows Update and HP Support Assistant: (do not skip any troubleshooting steps if you feel steps are repeating) 

To check for updates now, select the Start button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates.

Install updates from HP Support Assistant: Go to Download HP Support Assistant to install the tool.

1. To open HP Support Assistant, double-click the HP Support Assistant icon .
2. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
3. Click Check for updates and messages to scan for new updates.
4. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
5. Click the update name for a description, version number, and file size.
6. Select the box next to any updates you want to install, and then click Download and install.

Hope this helps! Keep me posted for further assistance.
