Aurora R13, stopped booting

If the system was in storage for two years, the backup battery that kept system date/time and BIOS settings may had been depleted.  First thing you need to do is to replace it with a new coin cell battery CR2032.  You can get it at local stores or source from online shopping for a dollar or two.

Follow the instructions below to replace the battery.  Make sure that the system is disconnected from power.

1. Lay the computer on the right side.
2. Press the battery-release lever away from the coin-cell battery until the coin-cell battery pops up.
3. Lift the coin-cell battery out of its socket.

After replacing a new coin cell battery, the next step is clearing CMOS via jumper and making adjustments to BIOS settings to match with hardware setup.

Refer to the Service Manual and taking precaution while working inside your computer.  Follow these steps to locate and clear system CMOS using jumper:

1. Turn off the computer and disconnect the power cable from the computer.
2. Remove the left-side cover.
3. Lay the computer on its right side.
4. Locate the 2-pin CMOS jumper on the system board.
5. Ensure that the jumper is on the pair of password pins (JM34).
6. Move the jumper to the pair of CMOS pins (JM12).
7. Plug the power cable to the computer.
8. Wait for 10 seconds for the CMOS to clear.
9. Disconnect the power cable from the computer.
10. Move the jumper to the pair of password pins (JM34).
11. Replace the left-side cover.

Once you complete clearing CMOS, reconnecting power and run system diagnostics scan to identify any hardware issue.  If there is no issue being identified, you will need to install operating system to the new replacement drive.  Hopefully, it was an SSD drive instead of the old spinning HDD.

For diagnostics scan, upon powering up the system, immediately tapping on F12 multiple times until you get a one time boot menu.  Select the diagnostics among the menu to launch ePSA diagnostic.  Or, it could be Support Assist Diagnostics on some Alienware models.

You can also observe the power status light that indicates the power status as well as the system diagnostic lights and associated problems.

After clearing any hardware issue, you can perform Windows installation using USB installer created by Windows Media Creation Tool.  Note that Win 10 will end its supports in a few months.

I did everything according to your instructions. Nothing has changed. The screen is still black and the light on the monitor is flashing.

Reseat all memory modules and simplify the system setup by temporarily remove discrete graphics and boot drive.  Connecting the integrated video port to one monitor only.  Except for mouse and keyboard, remove all USB external device, if any. 

Hopefully, the system will boot with error message and may provide you access to system BIOS settings.  Once you can access BIOS, reset BIOS default and adjusting system date and time.  Reboot into one time boot menu, via F12, select and run system diagnostics.  Reinstalling OS to bring system back to live.

If the no boot, no POST issue is persisted and there is no improvement, the system board maybe faulty.
