Hi, I am not very knowledgeable with computer customizing so I need insight. Basically, I wanted to play pc games on my macbook pro. I decided to purchase SSD hard drive and use already purchased windows 7 cd. I followed procedure of installing the SSD drive (Samsung brand) on to the macbook and simply installed the windows 7 cd. Afterward, I realized that my macbook lost all the macbook functions: keys on F1~F12 (which was expected). Moreover, I couldn't hear the sound and headphone plug hole had red light on. Graphic Card was not supported so I couldn't play the games... Overall, I have no idea why... I have followed the procedure in the net such as installing realtek hd audio program (still no sound). Can someone help me what I have done wrong and what I should have done in order to resolve the problem that I am facing!?!
