I was using my computer, a custom build, when it froze and as a result I switched it off, to reboot it. When I switched it back on there is now an error message. 'A disk read error occurred. Press Ctrl+Alt+Del to restart'. I have and it comes up with the same error. I have changed the SATA cable, but no success. The boot drive is a Samsung SSD, just over 2 years old, and my Motherboard is an Asus Z97-Pro. Is there a way to fix this?
