Corrupt/unreadable errors on my Vista latop related to IE, YIM and

I think it all started when I was talking on my MSN Messenger on my Vista
laptop and all of a sudden it logged me out in midconversation and then I
logged back in. The next day I started to get "Corrupt or unreadable file"
messages in C: (hard drive) that said YahooMessenger.exe and another exe for
AIM and yet another one for IE. I'm giving up on IE and switching to Mozilla
(no error message that I've seen).

BUT I want to clear up these corrupt/unreadable file error messages. I
uninstalled YIM and AIM and voila, no messages. But when I reinstalled them -
messages were back along with new corrupt/unread file messages for files I
don't know what they're about.



And I'm getting exception notices too. With strings of letters/numbers.



Oh and dskcheck just seizes up at 1 and 2 and 3 percent. And it runs every
bloody time I turn on the laptop. The error messages say I need to do it and
I WANT to but the thing just seizes up.



Is this a Vista glitch that they have a patch for? I'm hoping this all this
is.



Or do I need to download files from my recovery disk to write over the
corrupted files?

I read something XP related about going into Start and Run and typing sfc
/scannow but would that be relevant in Vista?



I'm still making payments on this laptop. I'd really love to have it last
longer than the loan. And I bought it because of stuff like this happening on
my XP desktop.



Any help here would be appreciated
