Der Bug Check 0x124 WHEA_UNCORRECTABLE_ERROR ist immer ein CPU Problem (mit Ausnahme von Alpha-Versionen von Software, das aber betrifft ausschließlich Entwickler), entweder die Spannung oder Taktung der CPU (99,5 %) oder ein Defekt in der CPU oder dessen Cache (0,5 %). Ein Auswerten des Minidumps bringt nichts.
Die Auswertung sihet dann typisch so aus:
