An HDD problem

Here's the story - about 3 yaers ago I bought a computer with 6.2 Gb WD HDD. About a year later the drive became a drive with bad clusters. I replaced it and in about 2 years the new drive also got some bad clusters. I bought an IBM HDD and in about a year it also got bad clusters.
Recently, I've upgraded to some newer hardware - new motherboard (Asus CUSL-2), new video card (MSI Geforce2MX), and also got a new IBM 30Gb drive. Last night the new drive (Been in use less than a month !!!) got some bad sectors.
I don't know what to think, I've replaced almost all the hardware inside the PC and I still got this bad sectors problem in all my HDDs. Is it the power supply ?
My configuration is :
Celeron 667 (not overclocked)
Asus CUSL-2 M/B
128 MB of 100 Mhz RAM
IBM 75 GXP 30 Gb HDD (7200 RPM)
MSI Geforce2MX video card

Appreciate your help.

That wasn't the case. I worked with this drive all right, and all of a sudden (in the middle of DivX movie, damn !) The PC froze. When I ran a Scandisk, it discovered a bad sector, a new one.
One more thing - there are no bad sectors from production, or at least souldn't be any. The HDD should be as clean as a baby's bottom in the day of birth.

My drive still works, but this is not the point. The point is - some data was damaged. That means - I have bad sectors appearing on ALL my HDDs and that's what worries me.

Hi, jObE.
Thanks for your help, but, again, I don't think this is it. When the HDD works propelry and all of a sudden it starts to make some strange noises (like spin down, spin up again, doing some activity and then spin down again), I think that the media became physically damaged. Which is fine for me, but what I can't understand is - why all the HDDs got bad sectors inside the same PC ?

The bad sectors that appeared are new and not from production failure. Those bad sectors caused some serious data loss.
