I have 4 Gb RAM on my 32 bit system, but I can only access a little over 2 Gb. How do I access the missing RAM. I realise that on a 64 bit system it reads all the RAM, but on the 32 bit Windows 7 shows 4 Gb but doesn't use it all. Some is allocated to the system, but there is a discrepancy, so some must be lying around doing nothing.

I have been to microsoft and read about 4Gb tuning, but the command (increaseuserva) in dcbedit.exe are not recognised in 7. This so far seem to be the only way to allocate 3 Gb free RAM. I am not too good with this stuff, can someone possibly help, or does someone know how to sort this?

Thanks in advance Terry
