i dont think you can do anything actually..Your pc starts gpu intensive task will of course stutter and move like it has been stabbed in the heart then move along like usual.
In other words both your cpu and gpu arent good enough to be playing the current lineup of games.I am sorry for such information.

 

[itchea]

then why it slows with icy tower?

 

[itchea]

and the game is working with 60 fps but sometimes it slows i mean pes 2010

 

[ghnader hsmithot]

yes your cpu and your gpu arent good enough.Once the game has one part that has very heavy graphics, due to your gpu being old it can cope with that much graphic details

 

[itchea]

so what i has to upgrade?

 

[ghnader hsmithot]

i am not sure if you can upgrade anything.BUt just to be sure what are your specs?

 

[itchea]

intel celeron 347 3.0ghz 512mb cache
gigabyte 945 gcm-s2l
1x1gb kingston 1x2gb but i dont know its name
nvidia geforce 8400 gs 512mb

 

[ghnader hsmithot]

How much are you willing to spend on the upgrade?
And please tell me of your psu.

 

[itchea]

about 600egp=100usd ^)^

 

[ghnader hsmithot]

I dont know about the Egyptian Market all that well however you could save up for a new pc.
I think the only thing you can upgrade with 100USD is just the gpu.
