Solved!
Go to SolutionHi @mobin_mo the BIOS boot list option UEFI is used by a drive with the new GPT format partition. If your drive has the old MBR format partition, do not enable UEFI.

Then hold the power button for 30 seconds. Then plug the CMOS battery back in and the Main battery, then place one stick back inside the system. Also what are the things that happened in your laptop? Did it still show the Alienware logo then shut off or just stay in a black screen? I would recommend staying away from overclocking settings too as that is usually messed with people that know what they need to do.

Hi @mobin_mo POST will not complete if RAM is not detected. Please reseat your RAM cards. If two RAM cards, put in only one at a time, to determine which RAM card does not work.

The Alienware 18 motherboard has 4 (2 banks of 2) RAM card slots, and these slots will only accept SODIMM Dual-channel DDR3L RAM cards.

That does not mean that the RAM cards have a fault. Something is not allowing POST to finish its hardware tests.

H @mobin_mo
5 beeps = Real Time Clock Power Failure = CMOS battery failure = Install new $10 coin cell battery DP/N 44YK6 or C8KT2.
