Gaming PCs are powerful systems, but like any complex technology, they can occasionally experience problems. Whether you’re dealing with crashing games, poor performance, or display issues, this guide will walk you through the most common problems and how to fix them.

1. PC Won’t Turn On

✅ Check:

• Power cable securely plugged into both the wall and PSU.

• PSU switch is turned on (“I”).

• Power button on the case is functional.

🛠️ Troubleshooting:

• Open the case and reseat power connectors (24-pin and 8-pin CPU).

• Try a different power outlet or cable.

• See our PC Won’t Turn On After Shipping guide for more details.

2. No Display or “No Signal” on Monitor

✅ Check:

• Monitor is powered on and input source is correct (HDMI, DisplayPort).

• Video cable is connected to the GPU, not the motherboard (if a GPU is installed).

🛠️ Troubleshooting:

• Reseat the GPU.

• Try a different video cable or monitor.

• Test RAM by booting with one stick at a time.

3. PC Randomly Shuts Down or Restarts

✅ Check:

• System temperatures (use software like HWMonitor or BIOS).

• Power supply wattage meets your system’s requirements.

🛠️ Troubleshooting:

• Ensure CPU and GPU fans are spinning.

• Reseat CPU cooler.

• Run a stress test to identify thermal issues.

• Replace PSU if underpowered or faulty.

4. Games Crashing or Freezing

✅ Check:

• Ensure your graphics drivers are up to date (NVIDIA/AMD website).

• Confirm that Windows updates are installed.

• Check for game-specific updates or patches.

🛠️ Troubleshooting:

• Lower in-game settings.

• Run RAM and disk diagnostics (e.g., MemTest86, CHKDSK).

• Temporarily disable any overclocks (CPU/GPU).

5. Low FPS or Stuttering in Games

✅ Check:

• GPU drivers and Windows are up to date.

• Background programs aren’t using too much CPU, RAM, or disk.

🛠️ Troubleshooting:

• Enable Game Mode in Windows.

• Turn off overlays (e.g., Discord, NVIDIA GeForce Experience).

• Set your GPU to “High Performance” in graphics settings.

6. Loud Fans or Overheating

✅ Check:

• Fans are free of dust and spinning correctly.

• Airflow is not blocked (keep vents clear).

🛠️ Troubleshooting:

• Clean dust from case, fans, and heatsinks.

• Replace thermal paste on CPU if it’s old.

• Consider adding case fans for better airflow.

7. USB Devices Not Working

✅ Check:

• Try different USB ports.

• Check if device works on another PC.

🛠️ Troubleshooting:

• Update chipset and USB drivers.

• Disable USB selective suspend in Windows power settings.

• For RGB peripherals, ensure software is running properly (iCUE, Synapse, etc.).

8. Blue Screen of Death (BSOD)

✅ Check:

• Note the error code displayed (e.g., MEMORY_MANAGEMENT, IRQL_NOT_LESS_OR_EQUAL).

• Run Windows Memory Diagnostic or MemTest86.

🛠️ Troubleshooting:

• Update drivers.

• Check disk health with CHKDSK or CrystalDiskInfo.

• Roll back recent Windows or driver updates if issue started after changes.

General Tips

• Keep all drivers (GPU, chipset, BIOS) up to date.

• Regularly clean dust from your PC.

• Don’t ignore error messages—Google the error code or contact support.

• Use monitoring tools to keep an eye on temps and performance:

  • HWMonitor / HWiNFO (system sensors)

  • MSI Afterburner (GPU usage & temps)

  • CrystalDiskInfo (storage health)
