Hi @christopherdistor Una sa lahat^_^, Suggestion lng. After reading old threads, comments etc., I would suggest to created new thread if you can. Since medyo hindi na updated karamihan ng threads dito so I guess we need to move forward for new threads. Anyway, I have few questions: Bagong bili ba ung PC mo? Bago mo ma experience yung issue, ano yung huling mga nangyari?(Install new hardware? Install new software?) After mo I troubleshoot, like linisin ung RAM, what else did you do? Possible cause: Power Supply issue - kc based sa statement mo ayaw na bumukas and nag auto shut na ung PC mo. What you can do: Isolation - Isolate mo ung mobo, proc, ram and psu. Kung kaya tanggalin sa case much better. Then try to start. If still an issue, try mo gumamit ng ibang PSU if may spare ka and make sure its working. Suggestion: if you cannot troubleshoot further aside than isolation, I suggest to contact or bring your unit sa technician nearest to your place. If this have been fixed already, it would be a great idea to share how it was fixed.
