I have had a ceiling fan with light kit installed for several years. Just got a new computer and now the light pulses (like a disco strobe in slow motion). Problem will sometimes correct itself while I am working on the computer, other times, I have to just turn light off and work in the dark. Any ideas?

What make/model is the fan?
