[SOLVED] SSD no longer recognised in BIOS

[itsno]

Hi, I have an ADATA SATA SU650 2.5" SSD (model number ASU650SS-240GT on which I had installed Windows 10 some 9 months ago. This SSD is not too old at around of 2 years of lifetime usage - so, I don't think time is the problem. Now when I boot up my system it shows me this message:

'Reboot and Select proper Boot device
or Insert Boot Media in selected Boot device and press a key_'

I have read similar posts to ascertain my problem but they have not helped me, leading to me creating a new post. This message has appeared before too, and I used to fix it by switching off my UPS, then, the main source of power, and undo my steps to get it working again.
As of last night, this has not been effective. To check, I removed the SSD from the computer and put it into an adapter to check whether it's recognised as an external storage device in my laptop, but to no avail.
My PC's specifications are given below.

GIGABYTE B75M-D3H (rev 1.1) with BIOS version F10
Intel i3-3220
4x2 GB Corsair RAM (1600 MHz)
Corsair VS550 SMPS
NVIDIA GeForce GTX 650 Ti (1GB VRAM)

I have some important files stored on the SSD and will definitely need them later - please help.
I will be very grateful of you.

If the Bios can't see the drive then neither will any software file recovery programs. I'm afraid you will need to send the drive out to a recovery specialist in order to get anything off of it.

In the future, please remember to backup important files. All drives die, even brand new ones. The more copies of your important files you have, stored on different devices, the safer from being lost they become.

If it is not seen in its original system and its BIOS, and not seen at all in a different system as a secondary drive...it is likely gone gone gone.

Being a totally unresponsive SSD, even a $$$ data recovery company is going to have issues getting anything from it.

I had a Sandisk SSD go suddenly, all at once. Just...gone.
All 605GB of the data was recovered from my daily backup routine.

Will ADATA's own recovery software work maybe? I can try to get out something myself since I can't go anywhere during the lockdown in my country.

Also, I never expected an SSD to go out so soon. Thank you guys both for the advice.

If the system can't see it, nothing at the consumer level will work.
