upgraded to 4 gb and it is only seeing 3gb, anybody know what happened to a
whole gig?

Might be wrong, but I think you need the Vista 64 to be able to see more
than 3gig of RAM

The system memory that is reported in the System Information dialog box in
Windows Vista is less than you expect if 4 GB of RAM is installed:

All 32-bit versions of Windows (XP as well as Vista), even though they
have a 4GB address space, can only use *around* 3.1GB of RAM. That's
because some of that space is used by hardware and not available to
the operating system and applications. The amount you can use varies,
depending on what hardware you have installed, but is usually around
3.1GB.

To see the whole 4GB, you would need to run 64-bit Vista (and that's a
whole different can of worms).

On the other hand, very few people need or can make effective use of
that much RAM. It's unlikely that you would see any difference in
performance between 3GB and 4GB, unless you run particularly
memory-hungry applications.
