When I open "My Computer" or "My Documents", my computer
takes a while to load the folders. It didn't take this
long before. Also the internet is much slower and
occasionally the internet freezes or an error box appears
and forces the computer to close internet explorer. The
internet connection works because I can still use msn
messenger but something is wrong with the browser. I
tried using Spybot and Ad-aware but it didn't help and I
didn't want to delete any neccessary internet files. I
can't restore the computer to a previous state because
system restore doesn't work for some weird reason.Before
scan disk wouldn't work but now it does. All of this
started a few months ago and I haven't found any
solutions yet. Please help.

Thanks
