Possibly the driver needs to be updated ???

Maybe bad/weak batteries ???

It's 12.7 mm https://www.lg.com/us/burners-drives/lg-GTA0N-internal-dvd-writer

I'd hold the reset for 30 seconds on the router and let it reboot. Be sure that distance or blockage is not a problem. I'd call Comcast support if the reset didn't work. .

I'd try to reload the installation on another clean USB and be sure to run hard drive diagnostics.

Have you reset the CMOS via the jumper and checked the battery. Also try the Acer reset Remove power and all cables from the desktop, and press and hold the power button for 30 seconds. Plug power back in to the desktop and see if the computer will power on.

Is it beeping if so what is the code ??

Looks good to me , as Billsay say, check your length specs.

You don't really have to mount the hard drives. A couple of years ago, I installed a SSD Sata drive and just used some plastic wire wraps around a cable. It was not HOT and no moving parts so being level is not a consideration. Just secure them as they don't bounce around if you're moving it.

Good Luck, Please post the results to help others.

You have to remove the front cover .Usually there is hidden clips or screws on the top and maybe sides. 🤔 Maybe you have to remove the top cover.

I think so.

Here is a link…

I think that it is these, as I viewed a motherboard on EBAY.

You're going to have to remove the panel in picture 1. It may me this cable. https://community.acer.com/en/discussion/717581/looking-for-power-cable-sata-15-pins-to-6-pins-on-motherboard-acer-1780#latest

No bag of parts ? Maybe if you post a picture of the insides or someone should be able to provide a lay out of your unit. Amazon has a kit that may work ???

Look in your box for a bag of cable & brackets. No instructions.

…. TESTING Thanks Billsey.

Create USB win drive on a another computer, then boot enable, reboot while tapping the F12 key . See my attachments
