How can i fix this.

A few weeks ago i was working on my laptop and suddenly my network stopped working. Found that wifi was missing and all the settings were gone. I called customer care they asked me to do bios reset and it worked. The next day it again happened and is causing problems on daily basis i simply power off the laptop and turn it on (very irritating while i am busy doing my work). And today even the Bluetooth icon has gone.

What should i do?
