A pic of the plant would be preferable in order to get an idea of what is going on with it.
Growing Oncs, I've had to deal with the kind of rot you're talking about a few times.
I've also dealt with Onc Gower Ramsey before when I was managing a greenhouse. I've not found them to be terribly difficult.
Some things to consider would be:
1. As was mentioned, keep the potting media/medium in mind. What is it? How well does it drain? How old is it?
2. What kind of pot is it? Different pots will have different properties.
3. Does it get cold drafts from being near the window?
4. What precisely is your watering schedule? Once a week? Twice a week?
5. Are you using water that is too cold?
6. Do you really know if the potting media/medium is drying out before you water again?
7. How are the roots on your plant?
8. How big is your pot size in comparison to the root mass?
9. What are the temperatures really like in the room where you have your Onc Gower Ramsey? Feeling the temperature is not acceptable; your body fools you. It is necessary to get a temperature reading from a thermometer in order to know what the temperature really is.
I'm sure you know this already, Cheryl, but just for the sake of writing it in - Onc Gower Ramsey is an intermediate to warm growing Oncidium hybrid. It does well in warmer conditions. I remembered how warm and humid our greenhouses were; and let me tell you, it was uncomfortably warm and humid during noon up until late afternoon/early evening.
