Issues with freezing and reverting to HDD as boot disk

WD Blue 500GB Internal SSD Solid State Drive - SATA 6Gb/s 2.5 Inch - WDS500G1B0A

I have had this SSD for about 2 months and then suddenly in the last week my computer froze over night and when I restarted it the computer reverted back to the HDD as the primary boot disk. After resetting in the BIOS back to the SSD after about 2 days the computer had to be restarted again and was again reverted to HDD as my primary boot disk.

What do I need to do to fix this problem.

I’d recommend testing the SSD for errors. If it passes the test try swapping the SATA ports your hard drives are using in order to confirm if this is a drive issue or a Motherboard issue.
