Alright I have 4GB of RAM and in the System Properties it shows 2.75GB, Although in the system information it shows that I have 4GB. All of the RAM was tested and is working. I know that the 32-bit version of Windows XP Pro supports up to 4GB but would I have to minus my video card which is 640mb and windows, etc... And then would that leave me with 2.75GB of RAM? If so then I would have to buy the 64-bit version of XP Pro?
I read about this in an eariler post:
Which I would need to buy the 64-bit version of xp? Thx XD:)
