Diagnose recurring low-memory warnings and heavy paging by checking installed RAM, process-level memory use, browser and application load, committed memory, and whether one program is growing abnormally.
Diagnose multitasking slowdown by reproducing the customer's normal workload and watching CPU, memory, paging, disk activity, background processes, and heat at the moment performance falls.
Adding RAM improves performance when the current workload is constrained by memory and paging, but it does not make the processor execute faster or solve storage, graphics, thermal, or software bottlenecks.
Decide whether a RAM upgrade is justified by comparing the customer's real workload with memory pressure, paging, installed capacity, storage activity, CPU load, and the computer's actual upgrade options.
Diagnose suspected faulty RAM using repeatable memory-test errors, crash patterns, recent upgrade history, module seating and compatibility, and controlled module or slot isolation where appropriate.
