Windows 7 Error Memory2.5Gb Ram

I have a laptop with win 7 installed. The problem is that win 7 see only 2.5 Gb ram
instead of 3 Gb (real).
So, please give me a helping hand in order to solve this problem.

Do you have any onboard graphic card?
You can enable 'Memory Remap' in your BIOS if it is listed

Yes i have a Graphic Card nVidia GeForce Gt 420M.
The option memory remap is not listed in my bios.

Then the 0.5GB may be hardware reserved for your 420M, theres nothing you can do, but you can add additional RAM

What i must do to run all of my Ram ?

You won't be able to use all your RAM as the 500MB is allocated to your 420M

Hi, LegendAndy, welcome to the Seven Forums. :)

Going by the figures you posted you are using all of your RAM. Take a screenshot of the memory usage bar in the "Resource Monitor" to which rich46 directed you. That would be very helpful. You will more than likely find yowanvista to be correct in stating the RAM you think you are missing is reserved for hardware.
