I have been having trouble playing old games on my 64bit system. At first I thought this was just a compatablity thing, but I've narrowed it down to something going on with DirectDraw and Direct3D. When I first do dxdiag it shows that DirectDraw is disabled and Direct3D works partially. If I decide to do a 64bit scan, it says everything is working fine. I have updated drivers, changed compatibility even tried installing 32bit windows but nothing seems to work. I really want to sort this problem out since I have a lot of games that have pretty much become useless.
