Where has my memory gone?

  Mi Casa 16:47 30 Nov 2009

I have an Aspire 7535g laptop originally running Vista but now Windows 7 under the free upgrade scheme.

Since upgrading,Computer Properties tells me that I have 4gb ram installed - correct - but only 2.37gb usable - mmm!

Why is this?

Are you using Windows 77 32bit or 64bit?

It is 32bit.

32-bit OS - there's your reason. KJBlake explains it well in his post at click here.

It may be possible to tweak the system to 'see' more by enabling the PAE - see click here or click here. However, there could be a downside to doing this - explained at click here under 'PAE-mode-induced driver compatibility issues'. G
