recovery file and asist button failed to reinstalled window correctly

Hi i got a sony vaio model SVE1511AENB 

When after recovery the window doesn’t function properly, problem are listed as

1. Vaio care doesn’t exist after the recovery. All vaio function are not working.
2. Touchpad doesn’t function at the start, need to press window button to make it function
3. After using for almost 30 mint some keys doesn’t function .
4. Some driver like USB port and other HDMI ports are not functioning.
5. Sound system seems functionless while using it for some time

PS: I have tried rectifying by pressing ASIST button and had followed the required steps for several times. In my opinion the software that crush. Could you please provide me the linked for fresh downloading of the required full software for viao including the viao care too. I have tried downloading for sony forum support the vaio care. But seems not working. Thank you so much, waiting for the reply.
