Graphics area diplay problem

Hello

I have a problem with graphics area of solidworks. I have attached a picture for reference. I can't see the graphics grey area when I start Solidworks or when I open a part or drawing. I have tried uninstalling and installing Solidworks and defragmenting my disk but, it doesnt help. I am using Solidworks 2013 SP1.

Can anyone please help?
