Motherboard is not a standard form factor, so a standard ATX board will not fit in the case. The case wiring itself is not standard ATX either. To replace the board with an aftermarket ATX board will require a new case. If you have the original memory, put it in and disconnect all other devices including USB devices and do a CMOS reset by removing the coin cell battery. It's not uncommon for aftermarket memory to act up, even if they have been working fine for months before. If that does not work and a BIOS recovery option does not work either, than a motherboard replacement will be your only choice. Answer from Vanadiel on dell.com

Thank you for the reply, and yes I am aware that I will need to change the case and PSU, most of the testing I did with the original memory and the only USB devices that where plugged in where mouse,keyboard and the thumb drive when it didn't work without it (just pressing CTRL+ESC). Didn't try doing the reset without the battery so I'll try that this evening when I get home.

June 12, 2022 -
After trying to turn on my pc it doesn’t turn on but it does emits one yellow blinking light every 5 seconds. My power supply is getting power because the green light lights up when I press the button on the back. I researched the diagnostic codes and according to the website it means “bios and rom failure”. I took it to the shop and they had it up and running immediately. My computer was working fine after that for a few days and then it started messing up again by not Turning on and blinking one yellow light again. I haven’t took it back to the shop because I managed to get it back up and running a few times on my own, But do anyone have any suggestions on how to fix this issue ? Idk what’s causing this is happen. And what does bios and rom failure means?

I had that happen once about a month or two after I got it. Unplugged the power source waited a minute, plugged back in and never had that issue again. Think it happened when I put it into sleep mode. And now never have put it to sleep again, tho never need to anyways. Just power down when I'm done playing. Not sure if that well help your issue, but worked for me.

Besides three amber how many white led blinks do you have? Blinking amber—Computer is experiencing a boot failure but the power-supply unit is functioning correctly.

I am not sure but I think it was 3,1 which would be cmos. But if I switch ram slots fro. 2/4 to 1/3 I get no blinking lights so I could be wrong on the color. I was using g skill ripjawsv 3600mhz. I have the original ram as well and put that back in but I can't get anything to come on the screen. Last time this happened I changed the frequency ram to the wrong on in bios and did a cmos reset and worked fine. For some reason when I tried shutting down I got a grey screen so idk what happened.

You can look up the error code in the owners manual. Remove the new RAM and power on. If everything works then clearly the issue is with the new RAM. Before reseating it make absolutely sure you bought the correct DIMMs

[SOLVED] - Aurora r11 and civ 6 blinking yellow | Tom's Hardware Forum
February 13, 2021 - My step son has an aurora r11 Alienware tower. When he launches civ 6 everything is fine until the game actually starts (he chose a civ and scenario and so on...) Once the game starts the tower starts to blink yellow. No pattern unless it's 1 1 1 1 1. If he return to the main menu it's stops and goes back to solid teal.
