If you only experience issues when you connect the HDD, it would tend to suggest that the HDD is faulty.

Can you connect the HDD to another PC to see if that PC starts to exhibit the same issues?
If this PC doesn't display any problems it may be the motherboard in your PC.

Another possibility is that the cables connecting the HDD to the motherboard (and/or power supply) may be damaged internally.

I had an issue a few years ago where my PC was taking ages to boot.
It turned out that the power cable plug connected to one of my optical drives was defective (i.e. jiggling the power cable caused the drive to lose power).

I will try the power cables thing, that's the only thing I can try. I don't have another pc to try my hard drive on it.
