Well, a 1650 is truly small for Resolve. Besides the speed, I'd imagine it has 4GB of VRAM which is VERY LITTLE for Resolve.
Unless your projects are VERY SIMPLE and no more than FHD, I'd recommend upgrading the GPU. If you are on a budget, you can get a 20 or 30 series for not much. Make sure it's got 8GB of VRAM or more.
And as Charles said, chances are Resolve is just complaining about the drivers - but that won't change the above
