HDD failures usally go with clicking sound and the drives spinning, but you don't seem to get that and the HDD should show problems when working, not only at boot I guess. I still think your PSU is dying, but perhaps a slow death. Not a heartattack like mine. But it's hard to know for sure without changing parts around, it sounds as if you will have solved the puzzle soon though.
You could take the PSU to the shop and let them measure the output. I did that to be sure it was the psu that had gone out. Connecting a new PSU is'nt that hard as long you have documentation on your motherboard layout. From this you can figure it out, no doubt. Just check if the connector to motherboard is ATX 2.0, most PSU have a adapter if you run a older motherboard. The ppl in the shop should sort that out for you.

Good thought, I think that is a realistic possebility. Now that you say it I remember that some weeks ago the fan in the PSU did made some kind of noise. I needed to repeatedly shake it a bit in order to get it running smoothly again. Since it has not come back, I forgot about it completely.

I keep that one in mind, thanks.
