A friend of mine built a brand new system on Gigabyte P67A-UD3R, 2500k, OCZ Vertex 2, Windows 7 Home Premium edition (everything is running stock). Everything worked fine for 2 months. Recently upon trying to get back into Windows from Sleep/Hibernate mode, nothing happened. He proceeded to restart the computer and was faced with "Loading Operating System...." black screen, followed by Boot Device Failure Error. What we have done thus far: 1) Reset the BIOS, loaded optimized defaults. 2) Tried IDE and AHCI settings in BIOS. 3) Reconnected the power and data cables for the SSD and to the motherboard. 4) Tried SATA 2 and SATA 3 ports on the motherboard. The motherboard simply won't re-detect the SSD listing Boot Device Failure upon post. The SSD power light is still on; so that it is getting proper power. The SSD is not detected in the BIOS either under Hard Disk Boot Priority Devices. Has the SSD failed? What should our next troubleshooting steps be?
