I have a fairly old Compaq Presario V2424nr. Windows XP is ending support tomorrow, so ill probably upgrade to 7. The processor is 64 bit, and my friends dad said that 64 bit computers can have more than 4 GB of ram. But the laptop can only go up to 2 GB. And Windows 7 32 bit needs at least 1 GB, and its not even fully 2 GB because the video card takes up 128 mb. What to do?
