GTX 1060M keeps Flashing

[NightFury1993]

Hi All,
I have this problem with GTX 1060M on hp omen laptop, when I disable nvidia GTX 1060 from device manager, it works fine but as soon as GPU is enabled, laptop freezes and continuously goes blank back and forth. The laptop is just 3 years old and the issue started when I was playing “Horizon Zero Dawn” and suddenly it crashed while I was on chrome browser for some time.
I tried DDU, complete reinstall win 10, rollback bios firmware, completely disassembled laptop and cleaned CPU GPU thermal paste but no luck.
One thing I noticed is when you try to switch tabs GPU usage is instantly spiked to 100% but if you try to watch some 4k/8k hdr 60fps videos on YouTube it works fine until you don’t switch tabs or hover mouse around, there GPU and clocks everything works as expected.
So I wonder why the laptop works perfectly fine even when playing 8k @60fps videos(youtube), watch netflix, prime etc. and uses full potential of GTX1060 until I try to switch or hover around.

Note: Laptop doesn't have intel HD graphics, it only has GTX 1060 display driver with G-Sync 144 Hz refresh rate. I have also shared the video link to showcase the issue, see there as soon as gpu is enabled video plays at 60fps and fully uses gpu power. But after hovering around it starts to flash. Is this a GPU failure or some short circuit ?

Please reply what can be done to fix this, the most annoying part is I didn't found a single article or video on this issue over the whole internet.

Try these steps. This may work out

1. Examine the adapter and power cord for physical damage
2. Test the power from the AC wall outlet to the notebook connector
3. Start the computer using the battery only
4. Check that the lid switch moves freely
5. When you have completed the troubleshooting steps, there should be power available to the computer. When you press the power button, the LEDs should glow, and you should hear the sounds of the fan and the hard drive spinning.
   • If the battery does not accept the charge or the notebook does not turn on without the AC adapter, contact HP to order a replacement battery.
   • If the LEDs do not glow, and there are no other indicators of power being available to the computer, contact HP for technical assistance in troubleshooting a potential problem with the AC power connection or the system board.
   • If the LEDs blink, or the computer beeps, but it does not start, go to HP Notebook PCs - Troubleshooting LED Blink Codes or Beep Codes During Startup or Boot.
   • If the LEDs glow but the computer does not start on either battery or AC power, go to Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot.
