  • Thanks for the suggestion... I tried this, and the monitor is still displaying the colored lines all over the place. Tried using other sources as well and it still has the horizontal lines across the display.
  • So I used the computer all day today. Just about an hour ago, the power supply stopped making noise. Hilarious. I’ll keep this post updated with the status as I use it. 
  • Yeah I could also go that route... I’ll let you know what happens either way. From talking with Best Buy and some other local computer shops, it’s common for Acer, HP and Dell to use “one-of-a-kind” components such as custom motherboards and power supplies. It works well, as long as the components work lol
  • I’m totally open to that solution if you can find me a power supply with 12V output for standby. Feel free to link anything you find. Appreciate the help. 
  • The problem is that it uses a special power supply that doesn’t conform to usual ATX specs. It’s impossible to just swap in another supply. I mentioned this before, but I’ll go over it again. The power supply only has 12V- there are no other rails for other voltages. It also has a special connector which is wired unlike…
  • Alright got the exchange and the new computer has the same audible noise from the power supply. The noise on this one is more sustained, sounds like electrical arcing from a bad connection. 
  • I'm not insisting on 12V standby... it's the design that Acer chose for the motherboard!! Looks like they are using the ATX12VO standard, where there is no 5V standby, and everything is now 12V. https://www.intel.com/content/dam/www/public/us/en/documents/guides/single-rail-power-supply-platform-atx12vo-design-guide.pdf I…
  • https://youtu.be/flBIoAI7bME This is the noise the power supply makes... the noise stops when there are no active tasks. The fan is not running during this video, and doesn't normally run, however it will run if the power supply gets hot, and the fan is very quiet. The noise sounds like a ticking sound when the computer is…
  • Ok, so I need to know if a regular ATX power supply will put out the 12V required for standby? I am not a computer specialist, but it's my understanding that a normal power supply does not put out 12V in standby, and only turns on the 12V power when the PS_ON signal is triggered. I have no idea how this Acer works, since…
  • I covered that Bill. It isn’t the fan. The power supply has a component which is making the noise. The component on the power supply pcb makes the noise even with the power supply fan completely disconnected. If you’d like a video so you can see that it isn’t the fan (which is quite evident when the fan is disconnected)…
