Please post a solution for the problem..(
is my Comp using less memory than installed physically???
In a fix please help!! (

P.S. My RAM is by G.Skill

One of your ram sticks may be malfunctioning, you should also know that 32-BIT operating systems can only use between 2.6 and 3.5 GB of ram.

To check if your ram is bad:

Download MemTest86

Burn it to CD/DVD using an ISO burner such as IMGBurn

Boot from the disc. (You may have to change your boot order via your BIOS)

You are running a x32 bit operating system witch is limited to 3.XX GB of RAM (it varies from system to system) in order to use the full 4GB you need to install x64 bit version of windows.

You probably don't have bad ram after all, I thought your system was only reporting 3GB, please be clearer in the beginning (the edit helped). It wouldn't hurt to run MemTest86 anyway, but make sure you run it when you're out at work or something, a proper test takes hours to complete.

If you have a Windows 7 installation DVD that's an upgrade or retail install, you can format and change to 64-bit. Make sure you backup your files first though, as a format will erase all data.

However, if your computer came with Windows 7 pre-installed via the manufacturer or you have an OEM disc then you'll need to purchase a new disc that is 64-bit. You can either get a 64-bit OEM disc, an upgrade disc or a retail disc. The last two come w/ both x86 & x64 as choices.

EDIT:
Anyone else feel like repeating me?

thnx that's helping but plz tell me is my computer not using the whole ram or is it just x86 problem?? Btw if i upgrade to 64-bit than will i be able to run crysis warhead cs1.6 and others??? and what about the softwares??? i play DOTA too!!

It's not utilizing all 4Gb because it is x86 - and you can still run those games in x86.

The majority of games won't use more than 2GB anyway.
