How to repair a laptop/notebook with dll file issues?
My Sony VAIO laptop has been affected, due to some unknown .dll files deletion. When I started it, it couldn't go any further, it got stuck at the start itself, saying that the "CRYPT32.DLL" file is missing and has to be reinstalled, which is not possible, as the start and logon are not possible due to the missing .dll file. They only thing it does is : turning on and saying to reinstall the CRYPT32.dll file. I can't access anything, nor the web browser.
When I bought the laptop I didn't get any windows CD as a backup to use when I have issues. (This is a bad point, they should have given me).
So, how can I repair it, without losing any of my existing files?
