I'll just quote what I said to another user. the x51 r1 and aurora r4 use the same command center, so the steps are the same. "It's actually rivatuner thats the problem. If you go into your settings of rivatuner disable 64 bit support in programs and everything will work fine. You will lose OSD functionality though. That is the easy way. Another way (recommend) is to add all the alienware programs to rivatuner and disable OSD (turn it off) for all the programs. There is like 10+ programs I believe. The main one is command center but I did them all to ignore any possible issues."
