Okay at first, I was able to access it. But then, since I wasn't able to use it as a full administrator (unable to save downloaded files to hard drive), I tried tweaking the security tab of its properties. I checked and unchecked some of the boxes for what the user can control, but since nothing worked, I accidentally unchecked all of the options for each group (since i thought that was the default setting), then I pressed OK. Now I can't change any of those settings and I can't even access my hard drive... I just bought this laptop and I don't wanna wreck it so early. Any help please? Thanks!
