When I turn it on, the light is a steady amber with no beeps. However, the operating system does not boot even when the cables are secure. I think that it is an issue with the power supply or the motherboard, but I'm not sure. If it helps, I have Ubuntu version Noble Numbat. I have successfully booted Ubuntu before, but one day it randomly stopped working

Hi @bobusoxen
Try a full power refresh and check if that resolves the problem.
Turn off the PC if it is on and disconnect the AC power from the PSU.
Open the case and locate and remove the coin cell battery from the motherboard.
When the battery is out, measure its voltage. If it is <2.6V DC or if the battery is >4-5 years old, replace it. The battery model number is stamped on the battery. If it is a CR2032 these are commonly available everywhere e.g. supermarkets.
Press and hold the PC Power On button for a full 30 seconds and then release it.
Reinsert the coin cell battery back into its holder on the motherboard, (+ve side up as marked on the battery).
Reassemble the PC, reconnect the AC power to the PSU, turn on the PC and check.
If it starts OK etc, there may be a message stating that the date and time are incorrect. This is normal as the BIOS has been reset back to factory default by the above procedure. Once the date and time have been corrected, the message won't appear the next to me that the PC is turned on.
Also any user definable BIOS settings that were changed by you to suit whatever system requirements you needed, these will have to be changed back again as well

I unplugged it while it was off, replaced the circular battery (same model, working, 3v), and turned it back on, but it didn't work
Just verifying that you also pressed and held th ePower button operated when the coin cell battery was out?
Try disconnecting the power from the PSU and reseating the ram modules (remove/replace) and check if it now works.
If still no good, try with 1 ram module inserted only
If no good try the other one and check.
Always disconnect the power before removing replacing ram modules. Do this every time!

@bobusoxen from teh manual "
IF THE POWERLIGHT IS STEADY AMBER — Power problem or internal device malfunction.
• Ensure that the 12-volt power connector (12V) is securely connected to the system board (motherboard) (see "System Board Components" on page 102).
• Ensure that the main power cable and front panel cable are securely connected to the system board (see "System Board Components" on page 102).
Here is the Dell™ Inspiron™ 531 Owner’s Manual start with page 102. You may need a multimeter to check the power going to the motherboard as well as the output of the power supply. Let us know what you find out.

@bobusoxen do you get anything showing on your screen or do you just get the amber power light and nothing else?

No. The monitor is blank even when connected and the inspiron is on.

UPDATE: My dad and I took a look, and we were thinking the motherboard is done. However, the fans are still running, and the lights are still working. Even after adding an SSD (There was no Hard Drive), the light still remained a steady amber

UPDATE: I decided to start testing the Power Supply Unit (It's the original PSU for the desktop) with a Multimeter and all wires came back working, but the PSU is only 300 watts max...
