Upgrade my Pc Win 7

Hi, I am Dyslexic. I am unable to utilize my PC upto fullest and wander around here n there for settings. I have got a Core 2 Duo 32 bit 4 GHz. config. - that's Quite old, But for now, it's not possible for me to Upgrade due to lack of $$$.. I would rather go for utilizing the whole upto the fullest... I want to get back to the basic as I am new to PC world Moreover, I own an Android - Which is Quite comfortable to me.. I have read somewhere about having 2 OS on a single PC.. So Win n Android will do for me.. Also kindly modify the Accessibility n Text to Speech contexts with Human like sounds rather than Robotic. I use Firefox for its Add-ons I know its slow, but I cant configure Myself. So kindly help me... I am also interested in studying Programming So kindly do whatever you like with my PC to give me its full Potential. In Short, Personalize it... Thank you. (( If you r a Tutor Plz. guide me to a Group of Students .. )) Thank you, once again...
