When i try to open up the asset store the screen remains at the blank grey screen.
The asset store window is notoriously slow. If it gets stuck you can click the little triangle & lines in the top right and select reload.
You’re usually better off browsing the webpage instead.
This question had been asked many times on Unity Answers (e.g. here, here, and here), with the most common solution being that you need to disable DX11 mode in your player settings.
When your project target is set to use Direct3D 11, that causes the editor to run in DX11 mode too. However, it doesn't look like you have a DX11-compatible graphics card (as can be seen in the title bar just at the top of your screenshot - it says "DX11 on a DX10 GPU"), which will cause some editor features not to work correctly, including the asset store window.
