Thankyou Kari for the answer. i really appreciate it. but but after i clicked the setup.exe of 64 bit installation, the box appeared and it was written "the version of this files is not compatible with the version of windows you're running. Check your computer system to see whether you need an x86 (32 bit) or x64 (64 bit) version of the program, and then contact the software publisher." what should i do? create 64 bit installation with media? Thanks.
Yes, it's capable but that doesn't mean it will run fast. Especially if you use the PC for gaming then installing 64 bit without upgrading the RAM from 3gb is going to make it run slower. At least that's my experience.
The installer, the program in your ISO which performs the installation, is also a 64 bit program. Therefore it does not work on 32 bit Windows. From your existing Windows desktop you can only launch 32 bit programs.
As told earlier in this thread the only way to install the 64 bit Windows to your computer is to boot the PC with 64 bit install media. You have had plenty of advice in this thread about how to create a Windows install DVD or USB from your ISO. Follow the instructions given.
To see the difference between 32 bit and 64 bit Windows, and to see how to check if your PC can run 64 bit Windows, see this Microsoft article: 32-bit and 64-bit Windows: frequently asked questions - Windows Help. This article is also a good read: Taking the mystery out of 64-bit Windows - Windows Help.
I agree with my fellow geek Greg, I wouldn't use a 64 Windows with just 3 GB of RAM.

If you have an older Dual Core processor then you might find it maxing out with half of the RAM unused if you add too much. My guess would be around 4-6 gb. Others may have suggestions about the optimal amount if you will update your System specs in the bottom left corner of post with mobo and PC model numbers.

You can look at how many slots you have, which are used and open, and find your RAM specs by running the Crucial System Scanner software to find out what type of memory is in your computer.
