I have a Dell Dimension 4600C that has been working great. The other day it wouldn't power up. I checked all connections. Came back to it the next day and it powered on just fine and has been up and running great since then. The difference now though is I have a very high pitched squealing coming from the machine.
I'm certain this is a capacitor as I've had this happen to other machines in the past. I checked and I don't see any visible leakage and physically touching all that are visible doesn't change the tone at all. All of these items lead me to believe the PS is my issue but I’m just looking for other options. Thanks in advance.
