How can I identify which Dell laptop component is causing random freezes?

The 5–10 second pauses do not identify SSD, RAM, or motherboard failure, especially because they occur under light and heavy use and Dell’s basic diagnostics passed. Treat this as a data-collection problem before replacing parts. Record each freeze time and whether pointer, audio, keyboard, network, and disk activity also stop. After the next freeze and recovery, review System and Application event logs around that time for disk, storage-controller, display-driver, WHEA, or application errors. Run perfmon /report while the machine is healthy and save the report. Update BIOS, chipset, storage, graphics, and network drivers only from Dell’s support page for the precise model, then retest one change at a time. A clean boot can separate third-party software from Windows and hardware. If freezes continue without a clear event, collect a Performance Monitor trace or manufacturer-supported memory and storage test. A WHEA, disk, or diagnostic failure should drive warranty or hardware service.
