Question Working SSD not recognized by BIOS after power supply died/moving to new case

Jun 11, 2021
So the SSD does not show up in the BIOS, tried different SATA/power cables. The other SSD and hard drive in the system are recognized. The one not recognized is also the boot disc with windows, the motherboard and components are all the same from a working system until the power supply died.

So the only difference is a brand new power supply and a new case. The new power supply also has more wattage than the last one. I've also have an SSD to USB 3 adapter that I tried it with another computer, and it is not recognized there also. It seems odd that a power supply and SSD would die at the same time. Any ideas on what to troubleshoot? Thanks
A sudden loss of power can cause a problem with the SSD's controller chip. You can try "Power Cycling" your SSD.

  1. Crack open your PC and remove the SATA data connection from your SSD, but leave the power in.
  2. Turn on your PC and leave it idling for 30-60 minutes.
  3. Turn off your PC and remove unplug the power from the SSD for at least 30 seconds.
  4. Now you can either repeat steps 2 and 3 (as many times as makes you feel OK) or plug everything back in and try to boot your PC normally.
