Dell Precision M6700 Screen Freezing with Lines and Black Screen
I am using a Dell Precision M6700 workstation and I have started facing a serious display issue. After I turn on the laptop and work for about 10 to 20 minutes the screen suddenly develops horizontal or vertical lines and then goes completely black.
The laptop stays powered on but I cannot see anything or continue my work. This happens every time I use it and I suspect it might be related to the GPU overheating or a hardware failure. Does anyone know if this is a driver issue or if my graphics card needs to be replaced?

Start with a screen diagnostic (hold the D key through powerup). Do the test screens show correctly? If not, it could be a screen problem.
Then run a full hardware diagnostic -- F12 at powerup. Do the faults appear while those are underway?
This is a 14 year old system, so anything is possible.

These laptops were very nice ... back then.
You say after 20 minutes, so I wonder if it's over-heating? You might want to give it a good cleaning inside (and check the fans).
You can also run it's ePSA Diagnotics.
If something like HWinfo64 does confirm over-heating, you might want to have an experienced technician re-apply the thermal-compound. But other than easy-fixes like that, as @ejn63 alludes to ... it's very old and not really worth fixing if expensive.
Of course, any Windows-11 install would be a forced one. But since it's a laptop, you may/may-not end-up with all the required 64-bit drivers you need (ie, a clean Device Manager).

OK so this laptop is old as the others have said, but that's maybe why it's still being used. The Precision M-series has a bit of a cult following like IBM's ThinkPads. The good thing is literally every part of these laptops are replaceable, as opposed to the newer rubbish where they aren't.
To verify if it's a screen or GPU issue, you could always try plugging in an external monitor and if the picture is fine then you know it's definitely a screen issue. If the picture is still messed up then it's most likely a GPU issue. That's the quickest and cheapest way to know where the problem is.

If agree with the overheating thought. If the laptop was brought up to Windows 11, be aware that there are no Windows 11 drivers for the NVidia cards, which may also cause a problem.
