We have used ACNS twice to repair our computer. The first was a hardware problem; the second was a software problem which required wiping the entire hard disk and reinstalling Vista and the original programs. Tyler made sure that I had the original CDs to restore my additional programs. He then saved my data and started the cleanup. In a short time and at a very reasonable cost, we were up and running again. I do not hesitate to recommend ACNS for any computer problems.
