annoying green flickering

[Charles-1955]

a few days ago, I started seeing annoying patches of bright-green flickering stripes in areas of my backgroung screen, and along the manu bar along the bottom of my screen

the entire screen goes flickering green for a moment when I re-boot.

Yesterday, I spend 90 minutes downloading and re-installing the Video Driver.  For the next hours, the laptop display was perfect!  After work, I closed it, and when I reopened it at home - still brilliant!

This morning, I opened it at the office and .... the annoying green flickers are back.  This firefox screen has no problems, my Live Mail has no problems, but when I open my file explorer, I get some red lines along the edge of some boxes, and the thumbnail previews of some jpg files flicker with green.

I bought the laptop in Dec 2014, so it is "out of warrantee" but my last Toshiba Windows-7 laptop is still going strong (it's just not fast enough for Windows 10) so I expected this one to last at least a few years.

Was it a mistake to buy an HP?

At my son's suggestion, I did some troubleshooting:

1- When I attach an external monitor to my laptop, it does NOT have distorted color, so the problem is not in the "brains" of the laptop, but in how it is translated to the display.

2- a "print screen" of a jpg that DOES show distortion on my laptop, does NOT show distortion when viewed on another machine.  This suggests - in his words - that the laptop is NOT "rendering badly" but rather "displaying badly."

Again, I feel that this is NOT a hardware issue, but an issue with the monitor driver, and - no, thank you - I don't want to spend ninety minutes every morning re-installing said monitor driver, even though the results are magnificent.
