Why does my computer’s power LED keep blinking amber but doesn’t display anything?
Then you need to remove the faulty unit and replace it with a good one. Just follow the procedure described at p.19 on the user manual, the size of the PSU you need to buy varies depending on the specific model you have, a common PS2 unit should fit into the tower, but you’d need an SFF unit (like this one) if you happen to have the smaller model. Here’s a list of the most common PSU form factors. Let us know how the repair goes and don’t hesitate to ask if you need more advice
Many reasons that will give you a yellow light. What has caused this issue, it was working fine and all of a sudden it stopped - was there a power glitch?, have you moved the computer as sometimes the memory and or other connections inside get loose. I would open the box if you are comfortable - ALWAYS UNPLUG THE POWER. clean the inside of the machine and check to see if nothing has been moved and the memory is installed properly. Hopefully that should resolve the problem else you may have a bad motherboard and or a power supply that needs replacement. Take it to a repair shop if you you are unable to work on it.
