I have just purchased a new HP PC running Vista Home Premium. I have had major problems with the new system, one of which is that System Restore won't work properly. It will load (after about 5 minutes) and will create a new restore point but, when I try restore to an earlier time, it goes through the motions for about 10 to 15 minutes but fails to restore. I get a message saying that due to an error (unspecified) no files were changed. Can anybody help please?
