The first step is to locate 64-bit drivers for each piece of hardware. If you cannot find one for certain pieces, take the leap of faith that Windows has a "built in" driver.

But, you have suggested the most valid of all tests. Try it.
There is plenty of help available here for any issues you encounter.
