Crazy problem with hard drive

[GWARslave]

Ok guys, I'm having a problem too difficult for me to solve w/o extra parts. I bought my WD 200JB drive about 2 years ago, worked fine up until 4-5 months ago. When I would restart my computer, my hdd would randomly restart itself either during the windows load screen or once it got to windows and would lock up the computer. By restart I mean making the click-shhhh sound the hard drive makes when you first turn on the computer. At first I thought it was loose connectors to the hard drive and it wasn't. So I opened up my power supply and found that some capacitors were blown so I thought ok, the psu isn't giving a steady amount of power causing my hdd to restart. So I got the psu replaced and the problem was gone. Until about a month ago. Same thing happens again, I ran a full diagnostic scan on the hard drive, no problems. Does anyone have ANY idea what could be the problem?

Uh... have you checked the PSU again to see if caps are leaking again?

no, I don't have the un-do stuff to remove the seal so it doesn't void the warranty, I had that done at work. I don't see why the psu would leak a second time if it's a totally different one. They were both Antec TreuPower 430w
