Dreambox Keeps Stopping

Recently encountered this problem after I had installed Rats new Enigma Channel list for DM800HD Clone. (The one that fixed the BT SPORT and Espn and ETC.) Basically the Dreambox stops every 20 mins as in completely stops, the channel and all. I cannot even switch the channel or turn it off or go to the menu, its as it completely freezes. Reboots. The only soloution is to plug it out from the back and then plug it in. But then same story every 20 mins and then comes back on. I have an OpenPli image. I was wondering what's the problem here: I tried using my friends psu,but the same encounter occurs(or it might be that his psu does not work either because he no longer uses his dreambox since around 5 months. 2 days ago I decided to unplug the dreambox but I kept it (psu) on in the socket just not plugged on to the dreambox. overnight. In the morning it worked perfect all day long till night again I did not unplug it. So what do I do now ?? Thanks
P.S. I even tried reinstalling the open pli image I use, I did a fresh new flashing, also service searching etc. but no luck.
