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.

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. The power-status light may blink amber or white according to predefined 'beep codes' indicating various failures. Table 1. Diagnostic light codes DIAGNOSTIC LIGHT CODES (AMBER, WHITE) PROBLEM DESCRIPTION 1,1 TPM Detection Failure 1,2 Unrecoverable SPI Flash Failure 1,5 EC unable to program i-Fuse 1,6 Generic catch-all for ungraceful EC code flow errors 1,7 Non-RPMC Flash on Boot Guard fused system 2,1 CPU configuration or CPU failure 2,2 System board: BIOS or Read-Only Memory (ROM) failure 2,3 No memory or Random-Access Memory (RAM) detected 2,4 Memory or Random-Access Memory (RAM) failure 2,5 Invalid memory installed 2,6 System board/Chipset Error 3,1 CMOS battery failure 3,2 PCI of Video card/chip failure 3,3 BIOS Recovery 1: BIOS recovery image not found 3,4 BIOS Recovery 2: Recovery image found but invalid 3,5 Power Rail Failure: EC ran into power sequencing failure 3,6 Flash corruption detected by SBIOS 4,1 Memory DIMM power rail failure 4,2 CPU Power cable connection issue

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.

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?

Hi, I had the same issue today. Everything was working fine except for the front LEDs and the alien head logo on the front was flashing 2x amber 1x white. But absolutely everything else seemed to be working just fine. I shut it down turning power completely off. I waited a few minutes and unplugged power supply from the wall. I waited about 10 minutes and plugged back in, started up again and it completely cleared the issue. I have no idea what caused this to happen in the first place.
