Calm down, cavalry is on it's way
To connect to the Pavilion's hard disk from the Mac, set up a share on the Pavilion. Easiest way to do this is to right-click on the folder you want to share and select Sharing and Security from the menu that appears. Activate and name the share, then hit the OK button. You'll notice the folder icon now has a little hand under it to show it's sharing.
Now from the Mac, select Network from the Go menu in the Finder. After a few seconds you'll get an icon representing the Windows computer. Hit the Connect button and logon to get a list of shares on the PC. Select the one you've created and it will appear.
To access the entire drive on the PC, select "Connect to server.." from the Finder's Go menu, and type
smb://<pavilion name>/C$
Once again, you will have to log onto the PC. This one will only work if the account you use to logon is in the PCs Administrators group.
The remote desktop method is by far the quickest for remote controlling Windows, although you can also install a VNC client. If I were you I'd stay with the Microsoft method though. The Remote Desktop client for Mac can be downloaded for free from
