Hi RaffaF1234,
Thank you for your Reply.
It seems that you have re installed windows therefore it should be clean from any corruption on the pc. It seems that this one seems to be on hardware side. Most likely the GPU of the pc or due to the Laptop's power issue. I highly suggest getting in touch with the Manufacturer of your laptop to get a hardware check or an updated driver for the GPU.
Best Regards,
