Last week I installed Windows 7 and I have just noticed that it only shows 2GB of RAM while I have 3GB.Can I fix this?

I am sure you installed Windows 7 beta 32 Bit ? . Windows 32 bit only recognizes only up to 4GB of ram? And this 4GB will vary from computer to computer depending on the hardware/software being used. There is actually nothing to "fix" because Windows is simply doing what it was programmed to do which is taking the other 1GB of ram and using it for other things. for example graphic card, sound card, application processes etc..

To be very clear, this is not a Windows 7 problem-- it's an x86 hardware problem.

[lambert]

It is a mathematical limit.

32-bit system can address: 2 to the power of 32 = 4.3 GB different addresses as it has to handle other tasks than the RAM ( resources, motherboard, expansion cards, including the graphics card), it remains only about 2.8 to 3.3 GB of RAM addressable following configuration PC.
Only 2.75 to 3.5 GB of RAM is actually recognized, and this due to x86 memory architecture.

Have you checked the BIOS?

Task Manager -->Performance --> Resource Monitor --> Memory -->Expand 'Physical Memory' in that location it shows "Hardware reserve (should be ~1MB for 64bit system), total, installed etc.

In short you cannot to use more than 3GB of RAM on a general-purpose windows 32 bit Computer. The anwser is to use 4GB is to upgrade to 64-bit Windows version is the recommended solution by Microsoft.
