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.
