I have not used my

I have not used my Hanspring PDA for a year but want to use it again. We had just put on a new video card due to a faulty fan. The palm pilot icon disapeared from the desktop, losing all my data. I have reinstalled handspring but it will not sychronize....the only change on my computer is the new video card. Can you help me with the sync? Thank you June, senior citizen P.S. It would be wonderful to find my old data, too.
