I have recently replaced several of the main components of my system due to a power failure after returning form holiday. Long story, which can be found here.

In the end I ended up with a new:

- PSU (EVGA 850w supernova)
- motherboard (MSA 970 Gaming)
- CPU (AMD 8-series)

These were added to my old parts which were primarily:

- GPU (Geforce Titan X, about 1 year old)
- HDD 1 (250 gb, used for apps)
- HDD 2 (1.5 TB, used for data)

Attaching all components together to the new PSU causes the computer to start / stop (i.e. all fans & lights come on, but only for about 1 second, and then it all stops). Attaching them one at a time, and I Have narrowed it down to HDD 2 that is causing the problem. If I disconnect HDD 2, the computer boots fine. I have tried different variations of connection including attaching to different positions along the SATA power cable, using different SATA power cables, and connecting only HDD 2 and not HDD 1. I have also cleaned off all dust thoroughly. None of these have worked.

This doesn't look to be a mechanical failure with the drive, but something related to the power connector. As this is my data drive (and it's been at least 1.5 years since any back-up!), I am obviously very keen to get this back on-line if I can. Any ideas would be most appreciated.

Cheers

Thanks. I don't have another PC in the house. I tried to disconnect the SATA data cable, and get the same result (i.e. start/stop).

Unfortunately that means there is something really bad with the HDD :sad:
If you really need that data on it, then you're gonna need a local repair shop to do it.
But I also recommend creating a new thread in the Storage forum and make the title "PC wont boot when HDD is connected to the PSU". The experts there may have another opinion. (they may guide u through changing the power connector or something)
