Acer Aspire 5740G problem

Hello, I am contacting here. Because I currently have a gaming problem

The game that I play is called Command and Conquer Renegade. It's an old game made in 2003.

Anyways when I am playing it the FPS is 60 but then I get FPS freeze from 60 to 5 for a few seconds then it goes back to normal, I have pretty much tried everything but I do not seem to have any luck.

I will copy and paste here from the Renegade gaming forum what I said.

I recorded it with my digital camera and uploaded it to the website. I just bought the laptop about 6 days ago brand new.

I am at loss at what is causing this. I even installed windows vista on a parition hard drive and it's still doing the same thing. I had my friend to install win 7 64 bit on his desktop computer and it runs fine. so bascially it's not the OS that is causing it.

It's still doing the FPS freeze when I am on window mode and I even checked the CPU usage when the FPS freeze starts the CPU percent drops down to 2%

I have updated all the stuff on the laptop, Bios, Chipset etc.

Any help would be greatly appreicted.

My msn is [email protected] if anyone wish to add me on MSN and help me sort out this problem? Surely someone will know what to do. Could it be the laptop is ie faulty? If so how do I find out it is?.

Thank you again.
