Question SSD not found by BIOS.

Motherboard: TB250-BTC PRO
Intel Celeron CPU
Western Digital Green 120gb SSD – Already formatted with Windows 10
GIGA BYTE X1200 PSU
CORSAIR 750x PSU

I have a problem that has almost beaten me. The SSD is not being seen. In the SATA Config tab of my BIOS all 6 of the SATA 3 ports are displayed as “empty”.

I have done the following so far;
  • I have used 2 PSU’s as I thought it could be a power issue. No luck.
  • Brought a new Western Digital Green SSD, with new SATA cable. Same Problem.
  • CSM is disabled.
  • Tried connecting to all 6 Sata3 ports.

I don’t think it’s a BIOS setting, so I can only think it’s the SATA3 Ports on the Motherboard have failed. How can I test for that, without purchasing a new motherboard. I have written to the manufacturer but they have not responded as of yet.

I have had it up and running before, but due to work commitments had to store it for 18 months.

Any ideas ?
