Very strange PC!
I have a workstation that is an ACER Power SK30. It has been running 24/7. One day it shut down and it would not re-start. When you pushed the on/off button the CPU fan would come on for a split second and then turn off. No Blue LCD lights on the front would come on. It has all the symptoms of a bad power supply so I replaced it with a power supply from another good PC (not an ACER). I get the same symptoms. I tried with just the mother board connections installed. I still the same symptoms. Used a NEW power supply, not from Acer and still have the same problem.
Here is my question; I have heard that you have to use an ACER power supply when a replacement is necessary. Does anyone know if this is true?
