Laptop turns off during GPU usage HP Omen 16-WD0016

Hello,

I own this laptop for about a year and had no issues until recently. The Laptop generally works normally until I use any software that requires strong GPU usage.

It is not an issue if I connect f. e. a 2nd monitor to the GPU HDMI port. But if I start a a video game that uses the GPU, or do some kind of video or graphic rendering the screen starts to flicker before turning black. Same goes for the Power light, which turns off and sporadicly on again for a few seconds.

The only option that I then have is pretty much get the timing right in pressing the Power button while the laptop is turning on again and hold it until it restarts. After the restart, the screen normally again turns a few times on and off again at the login screen and then normalizes.

I normally unplug the Power Connection when this happens, so that the Laptop stops trying to access the GPU and have at least the feeling that this makes things a bit faster until the Laptop works again normally.

To point out, there are not any kind of issues with the usage as long as I avoid the GPU. The device isn´t super hot, or not hotter than in the past and I also don´t here the GPU fans being louder.

I already updated and reinstalled the GPU drivers and tried different things like reducing the performance, but the outcome was still the same.

I didn´t find anything online that fully fits my issue, in cases that were at least a bit similar, the common suggestion was that it will most likely be related to the power supply.

Hope that somebody here can give some more insights.
