Right-click the CMD.EXE (command prompt) short-cut.

Choose "run as admin". If you get a security prompt, click "Yes". You should now see a command prompt (white text on a black background).

Type "BCDEDIT" without the quotes. Look at the output.

I'm interested in whether the word "removememory" is mentioned anywhere. If so, that may be at least contributing to your problem, especially if the same condition was present during your machine's 64-bit days when you observed the same "missing RAM" symptom.
i just tryed it and there was no mention of "removememory" i can upload a screen shot of it needed.

No need. I trust your ability to read

It is not particularly suprising that you've only got 3GB "usable" out of 4GB "installed" while running a 32-bit OS. That is quite common. Depending on the specific hardware, some of the memory addresses which would otherwise be used to describe RAM locations need to be allocated for hardware needs instead.

There is another, completely unrelated mechanism that's sometimes (mis)used to limit the amount of memory, and that's what I was aiming to check with the BCDEDIT command. Obviously, there's nothing there to see.

Thanks for all the help. so theres nothing i can do to get back the ram then as it all looks right and 64bit version has the same happen to it as well?

So far it appears anyone with a Geforce 9000/8000 series or whatever, it will allocate shared memory regardless of x86 or x64. Appears to try and get to 2 GB, dedicated VRAM + RAM.

Every reference to people losing RAM like this most seem to have a Geforce 9000 card. And it doesn't matter with platform they use x86 or x64. For example this person has a Geforce 9800 GTX+ and running x64: 7.25GB RAM Usable?, and this one has a Geforce 9800 GT: Windows 7 showing far less RAM than should be....

Very strange. My (Custom Built) system is using an gForce 8800 GTX and I am showing as usable ALL of my 8 GB installed system memory (4 x 2 gb sticks).

I really don't think it's got anything to do with the video card. The reasons for the OP's descrepancy under x64 would need to be separately investigated once/if they reinstall. Right now, they're apparently on a 32-bit build and it's all just guesses.

I have had both 64 and 32 bit windows 7 and vista on my pc all 4 OP systems have had same problem all showing 4GB ram but only 3 usable so I know it has nothing to do with it being on a 32 bit OP system. And I have clean installed them all every time to be sure it wasn’t the old OP system causing a problem.

You'll never get 4 GB on 32 bit.
64 bit is another story however.
If you really want that 4 GB, you must use x64. Not sure how to help you on that once you are x64. But you do need x64.

Think of it like this:

If you stay on 32 bit, there is absolutely 100% chance that you will never see 4GB usable.

If you change to 64 bit, then you do have a chance of that happening.

32 bit=impossible
64 bit=possible

Of course, it's your choice which OS you want to use. And for you to decide if it's worth moving to 64 bit to have your chance.

In my opinion, since it didn't show before as 4GB under x64, I'd say it's a chance not worth taking and be happy if you're satisfied with x86 otherwise.
