I had built a PC with PowerX motherboard, WD blue HDD, 2 DDR3 RAM sticks and Intel processor.
It worked for around 9 months. While working on it one fine day, it turned off all of a sudden without any prior notice or symptoms. When I tried to turn it on, only the power LED and the CPU fan turned on, no other response was there, not even the logo or BIOS screen showed up.
It was under a 12 months warranty, so I went to the store for getting it repaired/replaced. They said it will take a few days for repair.
Now on the components side, I was checking the HDD by plugging it to another old motherboard. For your information, this motherboard's model is D945GCCR which was released in the year 2007. The HDD didn't get detected. I tried tweaking settings in the MB's configuration, but it didn't get detected at all. A SATA CD drive was working though. It maybe the case that the MB didn't support this HDD, but I suspect that the HDD somehow got damaged.
The store repair person checked the RAM sticks by attaching it to another motherboard, but one of the sticks didn't work. I also asked them to check the HDD, but they were too reluctant to do that.
The only cause of this sudden failure of the 2 components must be attributed to the faulty motherboard. So my questions are, who will take the responsibility for these damaged components? Is there anything I can do about this? Or anything else that I should know about?
