Consistency screen?

[Radec]

Morning.
I just booted up my PC and a black screen came up with "checking disk c: consistency" or something.

Little info:
I bought this PC from a friend, the PSU failed on him so I bought and replaced it. When I switched it on right after a new PSU, I often saw the 'consistency' screen.
I formatted the whole hdd and installed W7 fresh, which I wanted to do anyway, and it's been fine for a while. Until that screen again.

Does anyone have any ideas on what I should do?
Did the old PSU damage the HDD when it would cut out during boots ect?

Thanks.

Is there an easy way to copy everything over to a new internal hdd?

And forgive my lack of knowledge, but if I were to just copy everything onto a new hdd, wouldn't that cause a new hdd to have problems? Since it's the files and stuff.
Or is it the actual drive itself that's' damaged?
