    But i have the minimum ram required to run graphics card is there anything relation between lack of ram and flickering screen??
  3. You may have the minimum ram for the GPU, but not for the game. You'll need more to run Crysis and everything else Windows has running in the background.
  4. Minimum spec's have _nothing_ to do with the problem he's describing... The Power Supply could of affected it, but you've ruled that out with the CX500.

    Shaswat, if you haven't sorted it by now I'd recommend testing with an alternate Monitor & Monitor cable. Try alternate graphics drivers as well, if problem still exists your graphics card is most likely faulty. If after testing or trying with another graphics card it's still doing the same thing, then I'd be looking at the Mainboard.

    As MajinCry was saying with the RAM, you do have a very under spec'd computer for running Crysis, given the price of RAM/Memory these days, put as much into your computer that you can afford will make quite a large difference.
