Unresponsive keys on keyboard
I have an early 2008 MacBook 13" a1181. Some keys have come unresponsive. I believe it started after I downloaded an android file transfer program so I can transfer some music from my phone to my laptop but I'm not exactly sure. If this problem stems from something I downloaded or if it's a software issue what can I do to reverse it? I don't have an external hard drive nor the OS X installation disc.
Thank you for your help in advance
Is this a good question?
