...and mass storage? For playing games its fast in 64 bit than in 32 please helpppppppppppppppppppppp

You need to contact Acer customer service, your lap top may not support 64 bit only 32 bit. The graphics card also may not support Vista with 64 bit system. You can also go to Microsoft Customer Support and there you will find a tool to down load that will check your system for Vista compatibility.
Hope this helps
