Question

you have installed a new computer with a quad - core 64 - bit processor, 6 gb of memory, and a pcie video card with 512 mb of memory. after installing the operating system, you see less than 4 gb of memory showing as available in windows. which of the following actions would most likely correct this issue?
update the memory controller driver in device manager.
install a 64 - bit version of the operating system.
disable the agp aperture in the bios.
flash the bios.

Explanation:

When a computer with more than 4GB of memory shows less than 4GB available in Windows, it is often because a 32 - bit operating system can only address up to approximately 4GB of memory. Installing a 64 - bit version of the operating system allows the computer to access the full amount of installed memory. Updating the memory controller driver may not solve the fundamental addressing issue. Disabling the AGP aperture in the BIOS is mainly related to graphics - related memory management and not the overall memory recognition problem. Flashing the BIOS is more for system - level hardware compatibility and not directly related to memory addressing in this case.

Answer:

Install a 64 - bit version of the operating system.
