Can my computer run a 64-bit version of Windows?
To run a 64-bit version of Windows, your computer must have a 64-bit-capable processor. If you are unsure whether your processor is 64-bit-capable, do the following:
1.
Open Performance Information and Tools by clicking the Start buttonWindows, and then clicking Control Panel. In the search box, type Performance Information and Tools, and then, in the list of results, click Performance Information and Tools.
2.
Click View and print detailed performance and system information.
I have the disc for 64 bit, what determines if I can upgrade to 64 bit, and is there any point? what would be the advantages?
You cannot do an upgrade from 32-bit to 64-bit.

This is true, but assuming you have a valid XP licence key you can still use the upgrade edition of windows 7 and save yourself about half the sticker price of the retail version. You'll lose all your data unless you back it up and re-transfer it once you've re-installed your programs on the new platform.
I have Win7 32 at the moment, but I also have the disc for Win7 64. My computer is capable of running 64, but would there be any real point in the upgarde, given that I only have 4mb RAM?
It depends on what you plan to do with it. If you mostly just do light work like Internet, email and word processing then it's pointless. You wouldn't see much improved performance. If you're doing something more processor intensive that works better with 64-bit then it might be worth doing.
PC gaming mainly. From what I can gather though, the boost only kicks in if you are using more than 4gigs RAM, so would there be any advantage, given that that's how much I have?
