vienmēr prieks, kad kaimiņam nomirst govs :D

Q: What causes the issue?
A: Typically, the memory components are more than 2-3 years old and suffer a functional failure when subjected to a power cycle event (turned off and on). The memory failure is attributed to a degradation mechanism in a specific memory circuit design.
