Final answer:
To diagnose and fix a computer that won't boot due to potential RAM issues, test all memory modules individually, retain the working ones, and ensure they are installed according to the motherboard's memory configuration recommendations.
Step-by-step explanation:
When addressing the issue of a computer that will not boot to Windows and emits several beeps, this typically indicates a hardware problem, often related to RAM.
First, you should power off the computer, remove all four 2-GB memory modules, and test them individually in the primary slot to determine which are functional.
Since you already have the knowledge that two modules (DIMM5 and DIMM6) are working and should be used to maximize memory usage, install these two modules in the motherboard while adhering to the recommended memory configurations, which often suggest slots for dual-channel configuration if available.
After ensuring that they are seated correctly, power on the computer. If it boots successfully, proceed to verify that the operating system recognizes the full 8 GB of RAM through the system option in the settings app.
The subject of this question falls under Computers and Technology.
The problem described relates to diagnosing and correcting issues with memory modules in a computer. The task is to identify which memory modules are not working and replace them with the two working modules. The goal is to maximize memory usage and ensure that all installed memory is detected by the system.
