Having problems with your Dell Dimension 2350 PC Desktop ?

Dell dimension 2350 pc turns off and on repeatedly

\015 I have a dell dimension 2350, pc. It is approx. 8 years old and up until two weeks ago, always ran fine. Recently at start up after being shut down longer then an hour, the fan that blows into the pc started sounding like maybe barrings were going bad, like a baseball card in spokes, kind of sound...after running for about ten minutes, the sound would stop. And then two weeks ago, in the middle of surfing the internet, the computer just completely shut down. When I tried to start it again, it would boot up to the desktop, and the shut down again. I let it sit for about an hour, and tried again, and this time it wouldn't even turn on. It just kept turning on and off, repeatedly, never reaching the desktop screen. \015\012I have put in a brand new power supply, exchanged hard drives, and changed the bracket for the heatsink.....\015\012Nothing worked....\015\012Any suggestions on what this problem might be, and HOW DO I FIX IT???\015\012Thanks\015
