So I have a HP DV6-T Quad Custom Edition laptop and its done this a few times before but ever since I installed Win 10 its being doing this a lot.

 

The issue is as you can see via the image below is that the screen will randomly start displaying a bunch of different lines and colors. I'm not sure if there is a technical name for what is happening here. I did update to the AMD 15.7 Win 10 driver yesterday and its still having the same issue.

These are my display adapters that are installed in the laptop. It has the HP Intel/AMD switchable graphics.

First, OEM's like HP make modifications to the drivers on a system in order to make the dual graphics cards work well together.

As such you should only use the HP video drivers.

 

On my Samsung laptop I have broken my video because of this and am unable to fix it without a full reinstall (I can't find the settings that control this).

In my case the AMD driver must be signed by Intel in order to work with the Samsung (and Intel) graphics drivers.

 

I would first suggest uninstalling all video related stuff, then download and install the drivers/video stuff from the HP website and see if that helps.

If HP doesn't offer Win10 drivers for your system, try installing the Win8/8.1 drivers in compatibility mode.

Also, this can be caused by excessively hot temperatures.  Monitor your temps with this free utility:  Also, monitor your system's temperatures with this free tool:  http://www.cpuid.com/softwares/hwmonitor.html
Blow out the vents/cooler with canned air to make sure that dust isn't causing this problem.  DO NOT USE an air compressor or a vacuum as they can damage the hardware.

Ya HP refuses to make new drivers for there computers. I got this in 2011 and they haven't given it a single update. If you're going to make a computer with switchable graphics you really need to keep it updated with new drivers.

Still, it's your best bet to try their older drivers and set them in compatibility mode.

If that doesn't fix it, then download the latest Win10 drivers from Intel and AMD and install them.

You may experience problems then also - but there's not much we can do to help with this as there are known video driver problems with some Win10 upgrades.

The "fix" is to do a clean install of Win10 (so you don't have any older drivers on the system) - but often this will limit the things that a system can do.  In one case at work, the boot time for a system like this stretched to 1½ minutes - but otherwise the system worked OK (it was an older HP also).

 

FWIW - I'm saving my money now and intend to get a new system after Win10 has been out for about 6 months.  I figure by that time they'll have worked most of the kinks out of it and it'll be relatively stable.
