I recently installed Internet explorer 6 from a disc supplied by PC advisor. Since then I have been unable to play freecell and the computer has got much slower. Last week I bought a HP photosmart printer and after installation of this everything is on a go slow. I continually have to do a disk cleanup to keep it working at all. I still appear to have 2.45GB of free disk space out of a possible 6.026GB. Can any one help me please?
