Memory, Virtual Memory, and where can you get memory to add (hint: Crucial Technology).

This is Yogesh Anand and I just have registered myself on your website and have a query if I could any solution for this, my query is :-
Its about "virtual memory" We all know what a virtual memory is, what it does, what is its impact. The problem is that or which I want to know about is what are the symptoms or is there any indication that tells us that it’s the time for increasing the virtual memory, How do we know about it? Any guesses ?
Your computer gets slower and your hard drive spends a lot of time with its light lit — because Windows is spending so much time swapping memory values that it’s not currently using to the hard drive, and bringing back the ones it needs now.
This happens more and more when you are running a lot of programs (including the add-ins that come with software and hardware installations that always want to preload or to run all the time. For example, Adobe Reader wants to preload itself, to take a couple seconds off the opening time when you need it. Microsoft Office and OpenOffice do, too — and preload critical parts when your computer boots. All this takes up memory. Of course, your firewall, antivirus, antispam, etc programs take up memory tool.
You run into the problems when you use Windows functions to swap to another program — Alt-Tab to swap to Excel, then Word, then your email program, then back to Word, etc.
I’ve gotten into virtual memory load-loops that took 10 minutes or longer for the computer to finally solve — it would load memory, do a few machine-level instructions (Load register, increment register, save register, etc), and then swap that program out to the hard drive so it could bring in the next one. When this happens, you can not do anything on the computer. That’s the real-world proof you need more memory.
Remember, though, that 32-bit Windows operating systems can only access 3.2 GB of RAM (real RAM memory), so the max you can effectively install is 4 GB for a 32-bit Windows OS. 64-bit Windows handles a LOT more physical RAM — and its capabilities are limited by Microsoft’s built-in limitations in its different versions of 64-bit Windows.
- Windows 7 64-bit Starter edition – max is 2 GB
- Windows 7 64-bit Home Basic edition – max is 8 GB
- Windows 7 64-bit Home Premium edition – max is 16 GB
- Windows 7 64-bit Professional edition – max is 192 GB<
- Windows 7 64-bit Ultimate edition – max is 192 GB
I haven’t seen any consumer motherboards that would handle more than 24 GB, though, 2 banks of triple channel memory at 4GB per DDR3 RAM modules (6 modules at 4 GB each).
When I need more memory where do I get it?
My favorite memory source is Crucial Technology.
