Why does windows 7 on ssd stop loading after a couple of days?

Question

Windows

Good afternoon! Guys, please tell me what could be the problem.
System I5 3470, gigabyte h77m-d3h 1155, r9 280x msi, ram 16gb kingston hyperx, corsair 650w, 1tb wd blue.
Was purchased and installed ssd kingston uv300 240GB under the system.
Transferred bios to achi, installed windows 7. Everything was great and worked flawlessly.
But after 2 days the computer did not boot (bootmgr is missing)
, while the ssd was defined in the BIOS not as originally kingston, but with an incomprehensible set of numbers / letters.
sinning on the bootloader or a crooked Windows, reinstalled the system.
As a result, again 2 days of work and the exact same problem surfaced again.
I went into the BIOS - there again, instead of the name of the ssd, a set of numbers / letters. Disconnected hdd, rebooted - ssd was defined in the BIOS as kingston and the system started up. But after the next reboot, the error returned.
It costs one ssd - it is determined incorrectly and does not start.
The bios version is the latest. Boot priorities are set correctly. The system in achi. What could be the problem? Tell me please .. I'm tormented.

Answer 1

try another sata cable. check the contacts for dirt, greasy traces. wipe. If it doesn't help, I would take it to the warranty.

Answer 2

The disk is defective, what is there to think?
If it's under warranty, return it under warranty, if not, throw it away.

Answer 3

disconnect all drives except ssd. install system with all drivers.
save the image to a third-party medium (for example, an external hdd)
if it falls again, then the fastest and most convenient way to recover from the image is.
A :
1. Update the BIOS of the motherboard.
2. update the ssd firmware
3. update the hdd firmware
4. perform multiple starts and shutdowns of the system during the day. (NOT REINSTALLATION!)
5. check the system performance for as long as possible (a week for example).
b:
1. update the BIOS of the motherboard (if already done, then do not repeat)
2. update the ssd firmware (if already done, then do not repeat)
3. disable hdd
4. make multiple starts and shutdowns of the system during the day. (NOT REINSTALLATION!)
5. check the system performance for as long as possible (a week for example).
if it doesn't help, check/repair/replace the ssd under warranty and hope for the best.
