What happened *


SPECS LISTED AT BOTTOM. I have had my custom built gaming pc for nearly a year now with much struggle. I’ve already rmad my board once and my graphics card twice. My pc was working perfectly fine for 3 months when the other day my ssd was no longer being detected by the motherboard in bios. At first I just figured that the ssd had died because it was about four or five years old and from another computer build. I was planning on ordering a new one when I started up my pc and noticed that my hard drive was no longer being detected in bios. This struck me as odd because my hard drive is only one and a half years old. I switched both the sata and power cables after completely powering down my pc and unplugging it (also I held down the power button for 30 seconds after to make sure the capacitors had been completely discharged). Still didn’t work. I plugged in a dvd drive from an old pc build to see if it would work using the same cables as my hard drive and interestingly enough it turned on. I went through my bios and made sure that all the sata controls were enabled and I even loaded optimize defaults as well as cleared the cmos. Still nothing. Any suggestions?

Trouble shooting steps taken*
1. Tried each storage drive by itself without any other being plugged in
2. Swapped both power cables and sata cables
3. Swapped ports that the sata cables were in and tried nearly each port available
4. Plugged in optical drive (dvd drive) into the same power and sata cables. DVD drive powered on and was detected by motherboard
5. Loaded optimized defaults
6. Cleared cmos
7. Tried other hard drive that I had in desk (did not work)*
