Why does my screen flicker every couple of seconds?

I have a Razer Blade Stealth late 2016 12.5” 4k i7 7500u. It flickers off and on, on the display every so often. I contacted Razer support and they said it was some graphic drivers that I was missing. I installed all the Intel 620 graphic drivers and it still keeps flickering. I isolated the issue by plugging in an external display and everything seemed fine. No flicker, everything was running flawless. My warranty already expired so I am trying to find solutions on how to fix this.

Normally flickering is caused by a faulty LCD cable, so that’s where I would start as that is the cheapest solution. Since the screen works on an external display, it’s not likely the motherboard, so we can rule that out for now. If the LCD cable doesn’t work, you can try replacing the LCD screen as well.

Ah I see. Well to add to this, I did rollback to the initial display driver just barely, that is on the Razer Website for this model and the flickering has completely stopped. Would it still be due to a fault in the LCD display or is it the driver itself?

If rolling the driver back fixed the issue, then I would say it's likely a driver issue. You can try to push the monitor back and fourth and see if it flickers. If it does, it's the LCD cable for sure.

I have finally found the answer! I changed my wifi driver to an intel dual band 7265. I attempted to install the drivers and tried to get it to connect. Unfortunately, I don’t think it was compatible with my system. I then clean booted my computer and restarted. Link to clean boot tutorial: https://support.microsoft.com/en-us/help.... I then uninstalled all of the Killer Wifi and Bluetooth drivers. That’s right all of them using Revo Uninstaller. I then reinstalled the m.2 Killer wifi module and the flickering stopped. My system automatically recognized it and it is able to use wifi and Bluetooth without the drivers. If you have this problem, its the Killer wifi/bluetooth software that caused it.
