It seems that within the last couple days something has happened to me pc that has erased a bunch of my icon pictures. About 1/5 of my icons on my desktop and my programs have changed to the 'unknown program' icon and the 'unknown exe' icon. The files all still load up properly, but this is very aggravating to deal with. Any ideas on how to fix it (p.s. I have already tried system restore with no luck) Thanks.
