I recently installed a Pioneer A07 into my stand-alone Matrox LX video editing system. The system has dual PIII processors and was custom built for video editing. Within days of installation, the motherboard failed. Could the DVD burner have any relationship with the failed board, or is this a coincidence?
Maybe. Have you heard of ESD, electrostatic discharge, damage? IC's today are VERY sensitive to static electricity. An IC can be damaged, not killed, but damaged by 30 volts of static without even touching it, just by being close. It takes a hundred times that to create a visible spark. A plastic ID badge typically carries a 300 volt charge. When you damage the IC, it may not die today, but it will eventually fail. Every time you apply power to the chip, the damage will get worse. As the component spacing inside IC's becomes smaller and smaller, the potential for ESD damage becomes greater. Testing has proven that even a chip mounted on a circuit board that is properly grounded can still be damaged by ESD.
If you installed the drive without proper antistatic grounding procedures, including at least a wrist strap, you may have severely damaged one of the numerous IC's on the motherboard that led to its failure. Of course, it could have been damaged previously and the last exposure was sufficient to finally kill it.
