Steam Machine units have begun shipping to early buyers. An early adopter posted on Reddit that the device functioned normally at first but stopped working after a Steam update installation. The system displayed a red error light, which the user described as indicating GPU failure. The incident involved a single unit among thousands of shipped machines. A red LED, rather than the usual blue indicator, suggests the device requires return for repair or replacement. Valve has faced component shortages that delayed the launch multiple times. Limited availability of replacement parts could extend service times for failed units. KitGuru said hardware failures can occur with any new device and hoped the case remains isolated.
