Recently I installed win 8 and increased my ram to 4 gb on my desktop but then most games such as the entire assassins creed series and gta stop responding after launch. i tries everything on google. i updated all programs yet no hope.
I have an intel dual core 2ghz processor, 4 gb ram of which only 2.9 is usable which i dont understand, win8 64bi with a radeon hd5800
