Over Ticklebum

I'm a relative 'newbie' so please don't be too rough with me!  I recently bought a Medion Erazer Defender P10 (30030059) and mightily pleased I was too - until after just a couple of days it started freezing, BSoD and rebooting on it's own accord. It was like it had a mind of its own - totally crazy. I did the all basics with virus checks, updating drivers etc and the usual stuff following steps on the net, but although there was a slight improvement, the underlying problem was obviously still there. Any sensible person would have taken it back to the seller or got some advice, but as it was bought through mail order, and I have a PC Tech repair shop nearby I took the quicker option and let their wizards have a look.  Its been a couple of days now and so far, I've had no major crashes or issues so perhaps they did the trick - however - the "Control Centre" for fan speed, keyboard backlights etc has completely disappeared and doesn't seem to exist anymore anywhere in the system. Its been wiped?  I have followed some earlier posts and links in this forum, but I only managed to download a diagnostic tool, but not the controls I was actually hoping for.  It's a minor inconvenience rather than a problem, but I can't find any downloads or links to get it back - or if it's even possible.  Any suggestions - or is it better to just let it go and not fiddle around?  Thanks in advance for any replies.  ...
