The Simple PS3 YLOD Fix:

- PS3 units are known for their propensity to overheat on a regular basis, causing a number of errors, though primarily the YLOD. Turn the unit off and allow to cool for half an hour.
- Remove all cables including power and carefully inspect for melted or heat damaged areas, then reconnect them to the unit, ensuring an accurate fit and connection.
- If your unit permits easy hard drive access (some models do, others do not) lightly push on the corners of the drive to ensure that it is not loose and is connected sufficiently.
