|This is what i found online in the owners manual:|
I F THE POWER LIGHT IS BLINKING AMBER — The computer is receiving electrical power, but an
internal power problem might exist.
(It sarts up everything is green and good to go then it shuts down and starts blinking amber)
• Ensure that the voltage selection switch is set to match the AC power at your location
• Ensure that the processor power cable is securely connected to the system board
it is set to 115 v
and i have checked all the power connections replaced memory but I have not reset graphic card.
Both the psu and the heat sink fans run until it shuts down
but they never change speeds I'm fairly sure previously i would hear the fans speed up in heavy use, but can't say for sure it may just have been the hd spinning.
