after few few days I install Bioshock again it cmoes back, i tried with dead space, it also does same,then I install Lost, it woks, but these 2 games were not working, whenever i click it few sec the screen black and comes back, plz help me ?

Very puzzling all these games are current DirectX spec and your drive Partitions are identical.
You did not indicate if your Hard drive has a full or near full Partition?
My Theory at the cause of this is Virtual drive space allocation Instead of using 1 sector it has to look at 4 and they may not be set to an equal amounts? a fullish partition will have a showdown on Processing times and from the sound of it the sector with the 2 games in it is just over that line.
A defrag may help temporarily have to do it on both partitions
A scan with CCleaner from www.ccleaner.com will clear out any old remnants of Old programs also cleans the Registry...
NOTE Is Powerful so untick on the List those items you want to Keep before running the scan (I run this before defragging) and Defrag times are very fast
Does not hit System files bar things like file indexes and the Prefetch file Folder (Do get the odd running glitch from this folder!<--- which holds cookies for programs) These can be deleted safely
