MY PC'S RAM IS ONLY 512 AND THE SYSTEMS REQUIREMENT SHOULD BE 1GB. CAN I STILL PLAY THE GAME??

Upgrade your ram to 1GB and update your directX software to the latest version.

Sadly, the system requirements for Fifa 11 under Windows Vista/7 cite 2GB of RAM, therefore I don't see it working. According to the wikipedia article though, if you're running Windows XP, you'll only require 1GB RAM, if you really want to play it, this could be worth looking into.

maybe this would help:

FIFA 10 (Fifa 2010) Minimum Requirements: Proc: 2.4 GHz single-core
RAM: 512 MB RAM for XP / 1 GB RAM for Vista
Video: 128 MB Geforce 6600 or better, Ati Radeon 9800 Pro or better, Support for Shader Model 2.0 or better, DirectX 9.0c
Sound: DirectX 9.0c compatible
HDD: 4.4 GB or more
Broadband Internet connection required for Installation and online gaming

when the game cannot play because VGA requirement, then u should buy a graphic card that at least appropriate with video minimum requirement.

hope this help.

Please upgrade your memory to 1GB so you can run Windows 7 on your laptop.

as i think you will be knowing the minimum system requirement 4 windows vista it s 512 mb ram ..as i think ur s is less than that so you may be facing the hanging problem .. if so i suggest u 2 upgrade ur ram to minimum 512 .... r u install windows xp SP2....
if u have 512 mb ram then there may problem with operating system this may be due 2 d virus attack some files have became unstable ... so reinstall ur vista ....
your problem will be solved...

Do you have shared ram on your laptop?, i mean if the graphic card use the same ram as systems then the ram will be shared between graphic and system, however to get the good result the 512 won't be enough try 1gb to get good performance.
