Overview:

Proper airflow is essential for maintaining performance and hardware longevity.

Common Issues:

- High CPU or GPU temperatures

- Loud fan noise

- Unstable performance during gaming or heavy workloads

Steps:

1. Plan air direction: Front/bottom intake, rear/top exhaust.

2. Clean regularly with compressed air.

3. Optimize cable routing.

4. Upgrade fans (PWM/fluid bearing).

5. Monitor temperatures (HWMonitor/NZXT CAM).

Pro Tip: A clean airflow setup can reduce temps by up to 10°C.

Overview: The BIOS handles booting, hardware compatibility, and system stability.
Common Issues:

• System not booting after new component installation

• RAM speed not recognized

• Random crashes after update
  Steps:

1. Identify your motherboard model.

2. Download the latest BIOS from the official site.

3. Format USB to FAT32 and copy the BIOS file.

4. Enter BIOS and launch flashing utility.

5. Enable XMP for RAM speed; adjust boot order and fan curves.
   Pro Tip: Update only when necessary—“If it’s stable, don’t risk it.”

Overview: Good cable management ensures strong airflow, safe connections, and professional appearance.
Common Issues:

• Loose connections causing shutdowns

• Drives or fans not detected

• Blocked airflow from tangled wiring
  Steps:

1. Route PSU cables behind the motherboard tray.

2. Secure with zip ties or Velcro straps.

3. Avoid sharp bends or tension.

4. Double-check all PSU and GPU connections.
   Pro Tip: Every PC built by Advait’s Tech Hub follows strict cable routing standards for safety and performance.

Overview: Dust is one of the most common causes of overheating and hardware degradation.
Common Issues:

• Fans running loudly

• Components overheating

• Random shutdowns
  Steps:

1. Power off and unplug the PC.

2. Use compressed air to blow dust out of fans, vents, and heatsinks.

3. Hold fans in place while cleaning to avoid damage.

4. Clean every 3–6 months.
   Pro Tip: Install dust filters on intake fans to reduce buildup and extend cleaning intervals.

Overview: Motherboard LEDs and beeps help identify faulty components before boot.
Common Issues:

• VGA, CPU, or DRAM lights stuck on

• System not posting
  Steps:

1. Refer to motherboard manual for code meanings.

2. Reseat RAM, GPU, and CPU power cables.

3. Test parts one by one.
   Pro Tip: Keep a digital copy of your motherboard manual handy—it’s your best diagnostic tool.

Overview: Fans regulate airflow and temperature across components.
Common Issues:

• Loud or rattling noise

• Fans not spinning or spinning too fast
  Steps:

1. Clean fan blades and bearings.

2. Check headers and power connectors.

3. Replace failing fans.

4. Balance intake vs exhaust for proper cooling.
   Pro Tip: Quality fans reduce heat and extend component life — use only premium brands.

Overview: GPU drives visual output and performance; often the source of VGA light errors.
Common Issues:

• No display signal

• VGA light stuck on motherboard

• Overheating during games
  Steps:

1. Reseat GPU in PCIe slot.

2. Ensure power cables are fully inserted.

3. Test different display ports or cables.

4. Update GPU drivers.
   Pro Tip: Always support your GPU with an anti-sag bracket to protect the motherboard slot.

Item descripOverview: Drives store critical data and degrade over time.
Common Issues:

• Slow performance

• Clicking sounds (HDD)

• Boot failures
  Steps:

1. Monitor SMART data using CrystalDiskInfo.

2. Back up data regularly.

3. Replace drives with high reallocation counts.

4. Keep SSD firmware updated.
   Pro Tip: Clone to a new SSD every 3–5 years to prevent data loss.tion

Overview: Proper installation ensures a stable, long-lasting system.
Common Issues:

• Bent CPU pins

• RAM not seated properly

• Loose cooler or GPU
  Steps:

1. Ground yourself to prevent static discharge.

2. Gently insert parts; never force connections.

3. Apply thermal paste correctly (pea-sized dot).

4. Verify all cables before first boot.
   Pro Tip: Test components outside the case first (bench test) for faster troubleshooting.

Overview: CMOS resets fix many no-boot or configuration problems.
Steps:

1. Locate the CMOS jumper (consult your motherboard manual).

2. Move it to the clear position for 10 seconds.

3. Return it to its original position and reboot.
   Pro Tip: Use a CMOS reset instead of removing the battery for safer troubleshooting.

Common Issues:

• Keys not responding

• Ghost typing

• Backlight malfunction
  Fixes:

1. Test the keyboard on another PC.

2. Update or reinstall drivers.

3. Clean debris between keys.

4. For mechanical keyboards, check for switch failure.
   Pro Tip: A quick USB port change solves 50% of keyboard issues instantly.

Overview: RGB lighting should enhance your setup — not complicate it.
Steps:

1. Use one control app (e.g., ASUS Aura, NZXT CAM).

2. Avoid connecting incompatible RGB headers (ARGB vs RGB).

3. Manage cables cleanly to prevent short circuits.
   Pro Tip: Keep lighting profiles subtle — looks professional and reduces power draw.

Common Issues:

• System boot loops

• Random crashes

• RAM not running at rated speed
  Fixes:

1. Reseat RAM sticks firmly.

2. Run MemTest86 for diagnostics.

3. Enable XMP in BIOS.

4. Replace defective sticks.
   Pro Tip: Always match RAM frequency and brand for multi-stick configurations.
