I just downloaded the service pack. I restarted my computer

computer. If anyone has can help me out with a solution
please, please do. Thank you.

Can you expand a little, when you say "cant access my hard-drive" what
exactly do you mean? You cant see it? You can click "Start>Run" and then
the drive letter?

Bit more info please

when i click start then go to my computer, the screen freezes, then a
message pops up. data execution prevention stating to protect your computer,
windows has closed this program.
it does this when i'm trying to access control panel also
i've turned off the firewall and still nothing has changed
if you need more info let me know.
