Study Notes
PC Hardware Exam Guide
- SATA Cable: A cable characterized by a wide, black connector. It's designed for a specific connection direction; the L-shape prevents incorrect connections
- CPU and SATA Data Cables: CPUs do not have SATA data cables connected to them. SATA data cables are exclusively for storage devices like hard drives and optical drives.
- Drive Bays: PC cases have different sized bays for various storage devices. Common types are 5.25" and 3.5" drive bays.
- Powering Down: Before working on a PC, shut down the system, turn off the power supply, and disconnect external cables (USB, headphones, monitor, etc.).
- Grounding: Use an anti-static wrist strap to prevent static electricity from damaging components.
- Hard Drive (HDD/SSD) Identification: Rectangular metal boxes typically 2.5" or 3.5" in size. Less rectangular than optical drives. Located in a bay, often near the back of the computer case. No sliding trays.
- Hard Drive Connections: Two cables connect to a hard drive. A SATA power cable (thicker, multicolor wires) connects to the PSU, and a SATA data cable (narrower, "L" shaped) connects it to the motherboard.
- Hard Drive Removal Steps: Disconnect the power and data cables. Locate the screws holding the drive in place. Unscrew or release the drive from its bracket. Carefully remove the drive.
- Optical Drive Identification: A wider, rectangular box, typically with a front-facing disc tray to insert discs. Larger and more square-shaped than hard drives, often occupying a 5.25" bay. Similar SATA power/data cable connections as hard drives.
- Optical Drive Removal Steps: Disconnect the SATA power and data cables. Locate the screws or release mechanism (some cases have tool-less brackets). Gently remove the drive.
- RAM Identification: RAM sticks are inserted into long parallel slots on the motherboard. A notch on the bottom prevents incorrect placement.
- RAM Removal Steps: Carefully press down on the plastic clips at either end of the RAM slot to open them. Lift the RAM straight up and out of the slot.
- Video Card Identification: A large, rectangular card with a fan(s) and heat sink, usually occupying multiple slots on the back of the case. Typically equipped with multiple connectors such as HDMI or DisplayPort.
- Video Card Placement: Placed in the PCIe slot near the bottom half of the computer case.
- Video Card Removal Steps: Disconnect any power cables from the video card. Locate and unscrew the brackets that secure the video card. Remove any retaining clips. Carefully slide the card out.
- CPU Location: Located under the heatsink/fan on the motherboard.
- PSU Location: A metal box with a fan and multiple cables, typically located at the bottom or top of the computer case.
- SATA Power/Data Location/Description: Wider, often L-shaped connectors from the PSU, and narrower L-shaped, connecting storage devices to the motherboard.
- CMOS Battery Location and Description: A small, silver coin cell battery. Located on the motherboard.
Troubleshooting and Reassembly
- Disconnecting Cables First: Always unplug cables before removing components to avoid damage.
- Force: Avoid forcing components; this could damage the hardware.
- Pictures: Take photos of the connections before removing parts to assist with reassembly.
- Original Locations: Put screws and other small items back in the original container.
- Cleanup: Use compressed air to remove dust from inside the computer case.
Specific Components Removal Notes
- Side Panel Screws: Screws are often located on the back of the side panel of the case, sometimes using thumb screws.
- Inside Case Components: Some hardware may have brackets requiring removal via screws.
