One of the capacitators are loose, so it's operation is in an intermittent kind of way... :-)
So why not just replace the capacitor? Unless it's a SMT unit, desoldering and replacing it shouldn't be a problem.
I inherited a Diamond Viper plus SB PCI sound card from a machine that'd been crushed by a car. (don't ask!) The Viper went into my daughter's machine and the SB PCI card got two capacitors replaced before I sold it to a friend. And yes, I did tell him the card's history.
