I have two issues, though they might be related.
The most annoying one are the vertical pinstripes. I will be going along, just fine and all of a sudden I'll get a string of TDR pop-ups and then the screen will just become a pinstripe mess. The entire screen is full, and you can't see anything else. If I wait it will often reboot itself. This only happens when I'm in Windows. It never happens on the lock screen or before, ONLY in Windows. I have verified that it happens on both the laptop screen and an external monitor. It doesn't happen all the time....sometimes it behaves for days. This is a photo of it. Then entire screen is like this.
The other problem is that the laptop will not boot from the battery and if I unplug it from the power supply it will power off in about 5 seconds. The battery indicator says it's full. I don't know if this could be related to the graphics problem or not but they started at the same time.
I've wandered around the net looking for solutions and have tried what seems to be everything to fix the problem with the TDR....but nothing works.
Do any of you have an idea what is causing it and how to fix it?
The laptop is the HP Envy Dv7-7230us. It came with Windows 8, upgraded to 8.1 and just a few days ago to 10. It's happened in all of them...
