Maplestory lag on half screen

Hi everyone,
I am new here and i am not an expert but i would like some help from some pple in the "know". I am having this problem playing a game called Maplestory.
Recently i had my hard drive replaced. Since then,reinstalled but something strange is happening.Inside the game....when i am in town,in particular Edelstein....right side of town ,no problems...but when i walk to the left side i start freezing up and it moves like in frame per 10 seconds or something.Took my PC to the shop and they could not find a solution to it.They reinstalled the Windows (XP pro)...still same problem. Now i don't have that problem in any of the other rooms/screens....only in this part of town.So strange.
Has anyone got any ideas as to what could be the problem?
here is some data on my Graphic card as i am not sure what you need:

I have more to add to my post....Since then i found out that i freeze wherever there is a lot of graphics,like nice scenery,busy graphics,in game....and where there are a lot of monsters and drops...not only in town.I guess in town i lag because it is new graphics and it is made really pretty.....Does that help?...What could it be? is it my graphic card?
Thanks

 

I have similar lag and stutter on Lord of the Rings Online, and I know my hardware can handle that game. I get it in really busy parts, like the main towns and hubs, because there's just so much people and there's too much going on for the server and connection to keep up. If I go outside town, the lag goes away.

After you've tried everything David suggested, if you still have this problem, lower your graphics settings, especially the ones that control spell effects, shadows, weather and the like. That might help.

 

Thank you for your replies.It is an older ThinkCentre from IBM.Recently it heated up real bad and shut down. I rang the IBM Help-Desk and the guy told me it could be a combination of different things.
Mother-Board suffered from the heat-up or
the graphic card not strong enough as it is a 5-6 years old PC

In any-case apparently it was not worth sending it in for repair as it would cost me more that what it is worth...and to replace things like Fan,motherboard,graphic card and a few more things....it would cost me as much as building a new one.
I can understand that for sure....so i went to the shop and asked them to build me one.I am getting it tomorrow and will tell you all the specifics of it.Seems a good one and apparently it will more than definitely handle the game and even more if i wanted to.
thank you for your help David and Mimsy. I really hope it will work well.
Will keep you updated.

 

Good call, and definitely a better use of your money than repairing an old system.

Let us know how it turns out!

 

Oh yeahhhhhhhhhh!!!!!!!!!!!!....works like a charm now.Absolutely wonderful.
so let's see.....not a big deal....basic things but reasonably new and good ....for what i need it.
i5 2400 3.1Ghz 1155 socket
WD 1000GB SATAIII 16MB
WINDOWS XP PRO
GA-P67A-UD3R 1155,DDR3,SATA3 USB3.0
LG DVD DUAL SATA BURNER
ATI RADEON HD 5770 1GB DDR5
STANDARD PSU 750W SILENCE4GB DDR3 1333

That's about it....at least it works well now....and only about $650...not too bad i guess. He also installed lots of little things like Photo shop,office,Kaspersky....so it is ok
Thank you for your help guys and girls

 

For $650, that's not a bad system... and more than capable of running Maple Story. Enjoy the game!
