11. Troubleshooting (Common)

Problem	Cause	Fix
No display	GPU not seated or monitor connected to motherboard	Reseat GPU, connect to GPU output
High temperatures	Poor airflow or improper cooler installation	Reinstall cooler, check fan directions
System won’t POST	RAM not seated or CPU issue	Reseat RAM, check CPU installation
Random crashes	Memory instability or PSU issues	Run memory test, check PSU voltages
Excessive noise	Fan curves too aggressive	Adjust fan curves in BIOS

12. Maintenance

Clean dust filters monthly
Monitor temperatures weekly for first month
Update drivers as needed
Reapply thermal paste every 2-3 years
