Lesson 1Graphics card (GPU): discrete vs integrated, power connectors; check PCIe slot seating, auxiliary power plugged, monitor port selectionLearn about separate graphics cards versus built-in ones, types of PCIe slots, and their power needs. You'll check if the card is well fitted, if extra power cables are connected, and choose the right port for your monitor to get good graphics and steady performance.
Built-in GPU versus separate GPU rolesPCIe x16 slot choice and its effect on speedEnsuring full fit and bracket alignmentNeeds for 6/8-pin PCIe power connectorsSelecting HDMI, DisplayPort, or DVI outputsTesting GPU under heavy use for stability problemsLesson 2Power supply (PSU): function, rails, wattage ratings; basic checks: PSU switch, voltmeter/PSU tester, peripheral connectors seatingUnderstand what a power supply does, its rails, efficiency, and power ratings. You'll check the back switch position, choose modular cables, ensure connectors are fitted well, and use testers or multimeters for simple power problem solving.

You'll check monitor input choice, cable condition, adapters, and USB ports so keyboards, mice, and screens work well during setup and fixing.
Monitor inputs: HDMI, DisplayPort, DVI, VGAChoosing the right monitor input sourceChecking cable pull relief and connector wearSafely using adapters and active changersUSB ports, hubs, and receiver placingBasic screen and input fixing 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'll check cooler fitting pressure, heat contact, fan direction, and header links so the system keeps safe temperatures and okay noise.
