so here is what i tried: -many of codec packs which seems to work for some people didn't for me
-tried that quad core in .ini file fix even if i have dual core processor (well didn't know what to do anymore)
-reinstalled atleast 5 times and started 3 new games
-updated my video and sound card drivers
-forced vsync off in .ini
-disabled AGP texture acceleration in dxdiag
-lowered my hardware sound acceleration level in dxdiag
-tried to play in windowed mode
-lowered resolution and other settings
-tried unofficial patch
-tried to play it with games for windows live installed and without it( when played without i did it once with games for windows live disabeled, and when it didn't worked i downloaded some .dll files to make it work)
-tried cleanboot
that is all i can remember now but probably tried more i have simmilar problem with fallout new vegas too so i guess if i fix this i can fix new vegas same way anyone knows what else i could try i would really like to play this game but with this crashes it's totally unplayable i wouldn't mind even if it crashes every one hour but here i'm talking about 5 minutes or even less.
ps. it is windows xp sp3
