How to change computer operating system from 32 Bits to 64 Bits?

I bought a new computer and I just installed a fresh copy of Windows 7 onto it (free from microsoft.com).



My computer is capable of running 64 bits however i do not know how to do this, does the monitor affect if you can change it from 32 bits to 64 bits?



does 1gb of video memory require 64 bits to run?

does 4gb ram also require 64 bits to run?



those were my 3 questions and here is a simple idea of what my computer is like:



4GB RAM

NIVIDIA GeForce 9500 GT (at the moment it says VGA memory 512mb)

CPU: AMD Atholon (tm) 64 X2 dual core 2.7 GHz (i have 2 CPUs)

COMPUTER: ACPI x64 based PC

MONITOR: Generic PnP Monitor (My monitor is old and crap until i buy a new one soon)

HARD DRIVE: 500gb S.A.T.AHow to change computer operating system from 32 Bits to 64 Bits?
You can run more than 1GB of video memory on a 32 bit operating system, but you cant run much more than 3gb of ram.



no, the monitor has no effect on that at all.



To get 64 bit, you have to buy a 64 bit version of windows, or if you have a copy that says it has both, you have to do a fresh install of the operating system, and when it asks if you want x86 (32 bit) or x64 (64 bit) you choose the x64.How to change computer operating system from 32 Bits to 64 Bits?
32 bit color is the best you can get. That has nothing to do with the bits of the operating system.

And yes, your videocard is a 512mb card, but you have another 1700 or so in virtual memory from your ram.

you will need to install a 64 bit operating system. To do this, you will need a copy of the 64 bit version of whichever operating system you are installing (for example I am installing Vista 64 bit tonight onto a computer I am building.



The monitor should not affect the change.



The amount of RAM that is used is dependant on the operating system. a 32 bit system will only recognize 3.5 to 4 gigs of ram (even if you have 8 gigs installed onto your mother board. A 64 bit system can handle much more ram, though most current motherboards max out at either 8 or 16 gigs of ram (which is overkill anyway. Unless you are a hard core graphics designer you will never need that much RAM, even 8 gigs starts to put you going %26quot;above and beyond%26quot;.How to change computer operating system from 32 Bits to 64 Bits?
