freezing problems & start up problems

I have a Toshiba satellite laptop, just barely over a year old. In Oct.
the hard drive went bad and sent it in to toshiba to have it replaced
under the warranty. They replaced it with a smaller hard drive first of
all and none of the keyboard short cuts work. I called them about the
problem and they told me I'd have to send the laptop back to them for
that problem!

Anywho, starting on tuesday afternoon, I went to start up the laptop,
and it took forever to load windows.. Once it did it froze up like after
like a minute. So I had to hard start the computer because the keyboard
short cuts don't work.

I've ran malware scanners, spyware scanners and virus scanners and
they've all come up clean. I did the Service Pack 2 update and it's
helped a little But this problem is still persistent. It's not as bad or
as frequent as it was. Start up is still very slow even after I did all
the above. I have plenty of space on the hard drive still. I'm just
stumped.


Anyone have any advice??
