I purchased a software package called Driver Detective. I only used it a few times because it screwed up my machine the last time I used it but in fairness it may have been my fault in not choosing the correct driver - I don't know.

I have no intention of paying them any more money. They have been most unhelpful in resolving my complaint. Regards Gerry Rigby read full review »
