I installed 4 GB of RAM in my computer Windows XP which has detected correctly 4096 MB, but the system information that 2 GB of Ram available.

I recently installed a maximum of 4 GB of RAM for my Win XP Home computer: four tips of 1024Mo in 4 available memory locations. Story: It came with 512 MB of RAM (256 MB two cards to 2 of the 4 slots). I sometimes treat files large image or video in a few applications, and if I do too much without saving the files, I get something like "...". not enough memory to complete... "and can not save either and lose an hour or two of work, all frozen, treatment and once had to turn off the computer by pulling the power plug (nothing else worked). Later, I added two boards of 1024 MB and moved the two 256 MB for the other two locations. The computer has detected correctly the RAM and showed 2,560.00 of available physical memory total MB of RAM in system information and available physical memory 2.00 GB (currently about 550 MB, current process). I put 4 GB page file. That helped a lot with the processing of these applications, but if do not attention, the same "...". not enough memory... "thing and I lost the job. So I added another 2 identical cards of 1 GB replacing the two planks of 256 MB. The 4 GB of RAM, I've added exact IS correct type for my computer. Set the pagefile to 1.5 times RAM available, etc, so that's it of OK. NOW THE PROBLEM, if it'S a PROBLEM: in the information system RAM is detected OK, showing 4,096.00 MB total physical memory, BUT not much more available memory: 2.16 GB available physical memory! Total virtual memory 2.00 GB remains the same in both cases, even if I put the pagefile of 12 GB. Page file space shows what I put in more added about 2 GB.
SO THE QUESTION: Is all the 4 GB of RAM (essentially) available for use with my operations high megabytes to image and video processing applications?  Or is Win XP steal my RAM and makes the page file? What happens here? You wish to know if I've lost $120,00 on two more strips of 1 GB of memory. Thanks loads, if someone can tell me.
Did not have a pretty good test in image/video applications to find out if I won anything yet. Always the same 550MO ongoing process. And Yes, I spent hours on the things in forums of online learning on the page file and RAM, most of which I knew already, but there is no explanation on the information system does not more than 2 GB of RAM available.
Thanks loads, if someone can tell me.

"My OS is Windows XP family 32-bit." End of the story for the possibility to use up to 4 GB of RAM. No, there is no way to magic, you can force a Windows 32-bit operating system to use all 4 GB of RAM. There is a difference between the question of whether a motherboard will support a certain amount of memory and an operating system be able to access memory. Sorry, you missed this fact in your research. Oh, and if you want to try one of the many Linux distros do not forget to use a 64-bit - after checking your processor is 64-bit also. That yours is not.
