Can a 32bit based computer be changed to 64bit without changing the motherboard?

Taking for example Dell Dimension 4700, or Dell Optiplex GX260.
Can i simply remove the processor and change it for an other one? because right now if i put a 64bit windows 7 disc it says the computer is not compatible.

Sometimes, if replacement cpu hardware compatible with the motherboard.

I would not recommending upgrading either one of these to Win7-64bit.  They are too old & too slow.  Win7-64bit needs a minimum of 4GB RAM.

well i have 4 gb installed but only 3 are useable and its sad because a lot of games cannot be played  smoothly on in

Dell Dimension 4700, Dell Optiplex GX260, both 32 bit hardware. You cannot upgrade either to any 64 bit cpu.

I have a Dell that can run 64 bit Windows 7. But I had a problem with it.  Somebody did an 'upgrade' by using a newer CPU with better performance. Sad to say, it was not fully compatible with eh chip set and the video was not reliable.
It is a DX 520. I had to find the older CPU. And it works fine now on windows 7. Now here is the sad part. I can not run Windows 8.1 on it. There is an instruction that is not found on the CPU.  End of the road.
Moral of the story: Older computers and not a good choice for new 64 bit Operating Systems. Avoid using a computer  over 7 years old unless you know for sure  it has been tested for 64 bit Windows.
