Can't seem to play any games

I am recently back to computer gaming after about 10 years absence.

I first tried playing starwars galactic battlegrounds but said something about there being a directdraw error.

So now I have downloaded the age of empires III trial and it won't play saying,
"Initialization error
Direct3D initialization failed. Possible causes:
Old or corrupted graphics driver
Direct3D improperly installed
Hardware accelerator disabled
Starting the application with the workstation locked.

Now I have checked to make sure I have directX 11 installed. I've also tried re-installing age of empires III.

Should I try re-installing directX? If so how do I go about that? I hope my GPU isn't corrupted or anything.

Any suggestions?
 
Solution
when I was running windows 8.1 some of my games had trouble running so I went back to windows 8 and every thing runs fine with no problems
I had to wipe my hard drive and re install windows 8 pro but this time I will not be updating to windows 8.1 I'm so glad I brought windows 8 and used Microsoft store to get windows 8.1 other wise I'll be out buying a copy of windows 8
