Detailed description:after upgrading my asus laptop by installing SIMMTRONICS 2133 MHz DDR4 4 GB Laptop (4GB DDR4 2133 RAM)

Initially it booted as this RAM is of same latency, size and frequency as that of the onboard ram of my laptop.

After a day i tried resetting the BIOS/UEFI settings to default and after which the laptop freezed while booting windows; I tried force shutdown by long pressing power button.

Now my system is unable to power on, it having black screen, charging LED is blinking twice and taking pause again blinking twice and taking pause continuously.

I tried following solutions but i am not even able to boot into BIOS or uefi also.

1. Tried removing upgraded RAM.

2. Tried CMOS reset by removing battery, by pressing power button for even 5 minutes.

3. Tried to boot by removing keyboard and touchpad.

There isn't any display or power supply problem. It's completely motherboard or BIOS related issue.
