Lesson 1Graphics card (GPU): discrete vs integrated, power connectors; check PCIe slot seating, auxiliary power plugged, monitor port selectionLearn about separate graphics cards compared to built-in ones, types of PCIe slots, and their power needs. You will check if the card is firmly in place, if extra power cables are connected, and pick the right port for the monitor to get good graphics and steady performance.
Built-in GPU versus separate GPU functionsChoosing PCIe x16 slot and its speed effectsMaking sure it's fully inserted and alignedNeeds for 6/8-pin PCIe power connectorsPicking HDMI, DisplayPort, or DVI connectionsTesting GPU when working hard for any problemsLesson 2Power supply (PSU): function, rails, wattage ratings; basic checks: PSU switch, voltmeter/PSU tester, peripheral connectors seatingUnderstand what a power supply does, its power lines, efficiency, and power capacity. You will check the back switch, choose modular cables, ensure connectors are secure, and use testers or multimeters for simple power fixes.

You will check monitor input choice, cable condition, adapters, and USB spots so keyboards, mice, and screens work well during setup and fixes.
Monitor inputs: HDMI, DisplayPort, DVI, VGAPicking the right monitor input sourceChecking cable pull relief and connector wearSafely using adapters and signal changersUSB spots, hubs, and receiver placingBasic screen and input fix stepsLesson 7Cooling: CPU cooler types, case fans, airflow patterns; check mounting pressure, fan headers and RPM reportingStudy CPU coolers, case fans, and air flow ways. You will check cooler fitting pressure, heat touch, fan direction, and header links so the system keeps safe heat levels and okay noise.
