Hi I recently downloaded Winrar and ever since it was installed my computer went down hill. I tried to uninstall it but it is still present. Now most of my files will not open and nor does windows media player. I am thinking of doind a system reformat, but need some advice on what to do. What i would like to do is to clean the whole system and start again, i have all the cds available and am able to back up my data. HELP PLEASEEEEE.
