Hello, I have a computer that worked fine I replaced the HDD with a new one powered it up and now the computer shuts itself down after anywhere from 45 seconds to 1 1/2 minutes. I then put the original HDD back in and it does the same thing.

I suppose in theory, but I've never heard of it and a decent PSU should have enough protection to prevent it.
I dont think HDD damage affects the PSU. But in your case it looks like the PSU is dying. What's your full computer specs and how old is your PC?
