I have upgraded 3 company laptops from Windows 7 to Windows 10. In every case, there were no issues before the upgrade, but immediately afterwards I started having trouble with the screen randomly showing fuzzy grayish blue "TV noise" on the entire screen. After a random period of time, usually a minute or so, the screen will revert to normal. Sometimes moving the mouse seems to trigger the return to normal. I've searched for a cause and the only conclusion that I can come up with is that the Win10 driver is not fully compatible with the graphics card. Has anyone else seen anything like this with Dell Latitude laptops?

Hi,

Screen artifacts might be a sign of overheating. Windows 10 is GPU accelerated which means you may have overheating problems on the older Dell laptops with insufficient cooling. Check out these registry keys for disabling some of the GPU hardware acceleration:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Avalon.Graphics\DisableHWAcceleration
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\HwSchMode Windows Defender is also GPU accelerated and can cause overheating on the older laptops. Some of the older laptops use a single heatsink for both the GPU and CPU. You can ask Windows Defender to limit it's CPU usage to help mitigate overheating.
Set-MpPreference -ScanAvgCPULoadFactor 5 I had to do this on my older Dell laptop after upgrading it to Windows 10... and the GPU still died.
Best Wishes,
-David Delaune

That's exactly the sort of thing that I was expecting. I'll give it a shot. Thanks for the details. Much appreciated.

I have figured out how to solve this problem. Nowhere on the internet have I come across the solution. It may be out there, but it is hard to find.
Here is how to solve the problem permanently:
1. Go to Control Panel > Intel (R) Graphics and Media.
2. Select /Click "Advanced".
3. Select/Click "Power" on the left.
4. On the Power drop down at the top, select "On Battery" to display the settings while on battery power.
5. Under the "Power Conversion Features", uncheck the "Display Refresh Rate Switching".
6. Click Apply and OK.
7. Problem is solved - Squiggly line artifacts gone.
Some additional information that I discovered while troubleshooting:
1. The problem ONLY occurred while on battery power.
2. The squiggly line artifacts would almost always appear after 1 to 2 minutes of inactivity followed by a tap or double tap on the mouse pad.
3. The squiggly line artifacts would disappear in about 30 seconds.
4. The squiggly line artifacts could be "locked in" if you opened notepad, trigger them to appear, and then started typing in notepad after they appeared. The squiggly line arrtifacts would remain until about 5 seconds after you stopped typing.
5. Never did the squiggly line artifacts prevent anything from being clicked.
6. The problem could not be triggered if an external monitor was connected (presumably because the monitor being plugged in changed the resolution and Refresh Rate Switching).
I have spent literally months trying to figure out how to trigger this problem and then how to solve it. I had already zeroed in on something with the graphics chip. With the help of a coworker, we discovered how to fix the problem. I hope this helps someone.

Yeah - if I am able to solve.

Your clues are far too obscure. As evidenced by the fact that only you can solve them. How we could guess "SHE" from ewe or sow ...

Not in any crossword I have ever done in the last 50+ years. And I never use Google to solve clues.

I think this is part of the difficulty, when there are clues within clues within clues... for me at least, it just becomes too many layers of abstraction.

You're lucky I got that. Most of the time when I want a word my brain refuses to handle the request in less than 24 hours.

yeah, saw that too. sad news indeed.

She was a famous singer in the 70's. She was also a feminist icon.
Go to the link to see.

Still doesn't ring a bell.

Wikipedia has a lot of links on famous people that died that day.
Sounds like more political correctness, hardly sincere.

Oh dear, you act is if you new here. Trollslayer left due to me.
And no, never heard of your Helen. If you post something like that, please include the "why"; if you don't you just trolling and showing off how PC you are.

Who cares if YOU never heard of her? I didn't post that for YOU.
If something doesn't involve you, then you don't have to respond to it.
