Hi,
Have a laptop with an rtx2060, 16GB of RAM, Windows 11 and i7-9750H, that had worked well for almost 3 years now.
It only black screens when plugged in and have played a game for about 20-30 mins. Then once I reset the PC (by holding down the power button as its the only thing I can do), it black screens the instant I run a game (some games it gets past the opening cutscene). Then once I leave the laptop for a couple of hours, this repeats. Other than this, the laptop works as well as before.
I have tried:
  • Updating both drivers and windows
  • Uninstalling my drivers through device manager
  • Using an external monitor (black screens as well - even when the game isn't up on this monitor)
  • Resetting my PC and reinstalling a new copy of windows
  • Trying a new plug socket
  • Press ⊞ Win + Ctrl + ⇧ Shift + B
  • Haven't been able to try a new charger since I don't own a second one
  • The performance on device manager also seem fine to me
When the laptop black screens, most times you still hear game audio and keyboard commands such as alt f4 work. Applications like discord also still work when black screened and when streaming the game, discord stops detecting the game. I have asked a couple of friends and the guys who built it (PC specialists - the laptop has worked and has been great, I'm just a little rough with it) which has lead me to taking it in to them this Friday unless if its a fix I can get done myself (don't trust myself to take it apart unless its a really easy fix).
The charging port can move out of position but I can just move it back into position with tweezers and don't think it's the reason why since the laptop still charges fine. I also haven't tried overclocking or messing with settings like that before so I don't think that's a reason why. However, I have gone into the bios and changed a setting page back to default as it wasn't detecting one of my drives with windows on it. However, that was months ago and my PC worked well for months up until now with no problems. I can also play games without any problems when not plugged in, it just performs a little worse (was like this before and think it is normal).

Any advice would be appreciated. Thanks
 
have you taken off the back cover and cleaned it from any dust build-up?
may be as simple as overheating.

when you reinstalled Windows, was that 'keeping my programs and settings' or 'keeping nothing'?
was it via the inbuilt Reset this PC feature or from a USB stick creased by the Windows Media Creation Tool utility?

"I'm just a little rough with it" raises some red flags too - especially after 3 years of use! :)

so have you already taken it to the PC specialist guys, or is that this Friday (tomorrow) ?

Taking it tomorrow,
Installed windows using cloud install but kept nothing. The temperature in the control panel doesn't go above 81 degrees on the GPU but I will try and find some compressed air to see if it's something else that's overheating.
Your probably right about being too rough with it though lmao. Will message back here if it works though.
(was going to have to take it in eventually anyway and got my parents to bring my desktop to Uni now so I should be good).
Thanks for your help :)
