I agree with John. Uninstall the crapware called "Tech Utilities" (most of those are geared to scare you into paying for a "solution" that either you don't truly need or that won't fix your issue). Then do a system restore, using the most recent one before you started having your graphics issue. If you do have to resort to a full system recovery be sure to back up all your data first! Doing a system restore (using a prior restore point) shouldn't require that but it's always prudent to have one just in case. Removing the graphics card from devices like you did is OK. It reinstalls automatically when you restart the system.
