I am using an NVIDIA 650i ultra motherboard. I have a dedicated video card, GeForce 8800GT OC (512 MB) and an Intel Core 2 duo Q6600 quad core processor installed. My memory which is a 4GB corsair DDR2 shows up fully in the BIOS as such but in Windows, it only shows 2.5 GB. Where did the rest of the 1.5GB go? I understand i will not see all 4GB in a 32 bit operating system but 1.5GB is too much to be lost. Please help me resolve this.
NB: I have tried enabling and disabling PAE but with no luck.
