oh dear, I didn't noticed, I thought it was Sunny. I saw Mai's first so I follow her instruction then I also see another one below so I was confused to why Sunny posted it twice. So I went back to look again.
I don't even have an audio cd for installation. I don't know what to do, if without audio, I can't watch anything or listen to anything and some of the program won't work without audio. -_-
Another problem, when I scroll down or up, it doesn't scroll normally, it scroll up and down like a warm? I don't know what happened, the space is about 127 GB free.
