Issues with crysis on windows 7

[arokia]

i just installed a fresh copy of windows 7 ultimate 64 bit and also installed crysis

now when playing the game i get an fps of 30 to 40 but after every 7 to 10 seconds the frame rates drop to 10 or 15...............as if the whole display just flickered

i dont really know what the problem could be...................i'm using a ati 4870x2 graphics card and a Q9550 quad core processor with a 6GB ram. i dont really understand why this keeps happening only in crysis..........................i've tried other games like nfs shift and they seem to work fine


my config is

processor : q9550 2.83GHz
ram : 6gb 1333hz
graphics card :4870x2 2GB
hard disk : 1.5TB



i think the reason could be because i've got my 1.5TB hard disk filled with 1TB of movies

partition details

C drive(OS): total: 300GB/used: 31GB
D drive : total: 1000GB/used: 900GB
E drive : total: 100GB/used: 50GB

if anyone had got an idea about this please do share

even defragementation did not help.....................i suppose it could be the new catalyst driver 10.2 which is causing the problem

problem solved............windows 7 was not the problem..........the problem was that its been 1year since i bought the 4870x2 and it was a little dusty especially in the fan area and the heat sink area..............so i sort of took a pin and removed the dust...........it took me about 30minutes to complete the process but it was worth it.

now crysis runs smoothly at 35 to 48fps at 1680 X 1050.....................on very high settings................and the noise from the gpu fan had also decreased.............

now i'm very happy with my ati 4870x2 graphics card because i dont have to spend another Rs 40000 on a new ati 5970.........................and can wait for the 6000 series to be realeased!!!!!!!!!!!!

+1 I have heard of people running into this problem so hopefully your experience will help some people out. Dusting out your heat sinks can be pretty helpful.
