I have a Pentium 133
with a 52x cd rom
and 56 MB ram, windows 98...
Diamond Stealth 64 Series (Diamond GT)
Fifa will run in my comp?
cause after the loading screen it goes back to windows

Well I'm not an expert on this stuff, but it sounds like you don't have DirectX 7.a. I had this problem with Direct X6, which comes on the CD.It wasn't until I installed Direct X7 that it fixed the problem
