Laptop suddenly not playing games it could before?

I have a Lenovo laptop that I got last year and it has worked very well. I've been playing dragon age inquisition and guild wars 2 on it since I got it but now they aren t working. When I try they both say things about drivers not working or directx not being right but I could play them both like last week and they were fine. I have nividia GeForce game ready drivers installed and updated and I just reset my laptop to try to fix the problem but they still aren t working. What could this be and how can I fix it?

You can try defragging your hard drive. Also you should download your graphics driver update again and when you are going to install it choose custom installation and then clean install. Hope this works.
