Solve : Windows Memory problem (upgrade problem)?

1.	Solve : Windows Memory problem (upgrade problem)?
Answer» Hi, I am having a problem upgrading my memory for my HP Media center PC m7360N. I bought it with 2GB of memory already installed and am trying to install 2 gb's more. I purchased 2 1GB chips PNY PC2-4200 (533MHz) it's also compatible with PC2-3200 (400MHz) when I boot up my BIOS is able to detect the entire 4gb's 1GB each chip.. when I get log on to WINDOWS it can only see 3.5gb's NOTHING more.. I have tried changing order of the chips but can't seem to get it to work.. When I go system information I am told it sees 4GB.. but under system properties or task manager they only are able to see 3.5GB I am trying to get my task manager and system properties to see the rest of the memory.. I was told that my video card may be the problem but I don' think so.. it's a nvidia geforce 9800gt I believe 1GB of memory (can't remember right now) below is a copy of my system information thanks for any help in advance..

*32bit OS is CAPABLE of seeing 4gb of installed RAM. (I've seen it under system properties. this varies from vendor)
*it will only use from 2gb to 3.6gb because certain devices reserve address space for their use below the 4gb limit
*I had 2 1Gb video cards installed on Vista SP1 - these were taking 256MB each consumed 512MB (although this is not the case)
