Phalaenopsis orchid dying/dead?

[May]

Well, this is my second time at trying to plant an orchid. I've had it for about 4 months. The flowers started falling off, but I thought that was normal due to repotting. Today I saw all the leaves had falled off. They were all as green as when I purchased it. So I had no idea they were barely hanging on. I dug it out carefully to check the roots. Unlike my last one where the leafs were all yellow with grey roots, these look a yellow green. The roots are mostly firm. There is about three with grey tips and a few that look like they want to turn brown. None are mushy. My question is can I save it? Should I find a bark and place it on it? I'm not sure if I over watered or not watered it enough so not sure how to save it if there is a chance of saving it. Any advice is appreciated, thanks. I attached a picture as well.
