Still cannot run FEAR

I have 2.8Ghz Pentium D

4 x 512Mb DDR2 667Mhx RAM

ATI x1600pro 128Mb(512 hypermemory) @ 540/920

5.1 channel sound

Intel DQ965GF  motherboard

Windows Xp Professional SP2

the game installs fine but as soon as I launch FEAR I get a black screen. I then have to exit to windows and in task manager it say it is not responding. funny thing is that I dont see any error messages. Help anyone

I also got the same problem before , uninstall any extra media codecs installed in ur P.C ( its written in the games readme also). Later after uninstalling the media codecs the game ran fine for me .
