My computer specs are Intel Core i7 2.50Ghz 16GB RAM, NVIDIA GeForce GT 750M. I have been minimizing and clicking on different views for it to show up.

Thank you.

I am running Windows 8.1 on my Pc and it has a 4 GB RAM, AMD A8 CPU, Generic PnP graphics (1600×900@60Hz) and 698 GB in storage space left. What could be the issue? How can I solve it?
