My computer doesnt start any kind of "recent" game, i played mafia correctly, and grand theft auto san andreas, but trying to run call of duty black ops 2 or mafia 2 gives me 0x0000007b error, on both games, and it used to give me that error on minecraft, but now it doesnt. i have checked dxdiag, tried to update directx( it was currently running newest version so it wouldnt let me update), and unisntalled and installed Visual c++ runtime from 2005 2008 2010 and 2012, both 64 and 32bits, from my W7 ultimate 64 bits computer with a Intel Q9450 @ 3.02Ghz 4gb of ram and a hd6850, what could i try instead of formatting?
