I have installed Windows 7 32bit and I have 4GB of RAM. The computer boot fine but after a while when I click on the Hard Drive Folder I just get a White Screen. However, W7 only reports 2.96 GB Ram usable while it does recognize there are 4GBs. Previously I had Vista 32Bit with SP1 and that fully recognized my 4GB. Can any one tell me that why does my Windows 7 32bit does not support 4GB Ram? any one knows about it? Please help me out to resolve the above issue. Thanks.
