Greetings,

The obvious question I have is, "What model / make / year is your machine?"

Speculation -> It is not likely Windows XP is the issue, so your problem begins to point towards the Bios (age - which is also unlikely if your machine is newer than 2000) or perhaps some on-board Mobo device that is stealing primary memory from the overall pool.

I wouldn't think it would be a problem with the physical memory as some of the available memory is recognized. But without more details, it is hard to guess.

Windows XP has issues when the amount of memory inside the computer reaches the 4Gb point. This doesn't affect XP 64-bit, nor will it affect Windows Vista next year.

In lieu of this, quite a lot of motherboards at this time don't give you the full 4Gb when you put it in, or run the memory at a slower speed or not report the full amount.

XP (and DxDiag) report what the BIOS sees, so if BIOS is only reporting 3.2Gb of memory, Windows will only report 3.2Gb. CPU-Z gets down on a deeper level though for its information.
