    4. cables off one pin
    5. red line of cable not on pin 1
    6. loosened connectors
    7. cables getting in the way of the CPU fan - fan does not run or makes noise
    8. cables being pushed inside the mechanisms of floppy disks
    9. loose mounting of the motherboard
    10. motherboard touching case
    11. cables to motherboard have black wires together (Check for correct wire configuration

    12. loose connections from the motherboard to a device
    13. ports not securely in place
    14. fan not securely on processor
