Anyway, I have 2 problems on hand now, both caused by the same reason:
I was wanting to clear out junk from my laptop and thus I referred to an IT magazine.
I used a tool called Duplicate Finder by Brooks Younce Software.
After I used the software and rebooted, all my drivers were corrupt, Photoshop CS2 wouldn't work, and lots of other things happened.
Well, I solved those problems, but..
1.) When I try to connect to a Local Area Network, it doesn't assign me anything.. the details box is empty. Totally blank. And, when I click Repair, it says 'TCP/IP is not enabled for this connection. Cannot proceed.'
I already Googled it up, and tried most workarounds, but it won't work.. and I'm left with a dead laptop that won't connect to the Internet (through the ethernet port).
2.) The Fn, S1 and S2 keys on my keyboard isn't working. I already reinstalled the drivers for my laptop but still it won't work.
Please help, I'm on the verge of sending it back to Sony Center...
