direct connection? or via a router? Try manually sharing each file you wish to share, (right click, share with everyone etc etc) just to test. Also, disable firewall and anti virus, also for testing process. Once you have done this, go to my computer, left panel, click on network. there you should see your other PC's name. Click on it and if your shared item is not there, then click on the other PC's name, then users, then name again, then desktop (make sure your shared folder is on the other PC's desktop). Also make sure you've created a home network. I could be way off, im no PC guru, but this is how i share things off our PC's and it works 100%.
