Problem fixed?

I know the discussion has been very alive on the comments, but I wanted to state a couple of points:

• Many users are experiencing trouble with the P-7811FX series laptop; these go from hang-ups to stuff that looks even worse
• Almost as many users are also experiencing terrible customer service and technical support: rude people on the phone, bad repair jobs, necessity of repeated technical intervention
• Finally, a subset of users found out that the problem can be fixed by lowering the performance of the graphics card using advanced tools like Rivatuner, which defeats the purpose of a gaming laptop

Please let me know your experiences with Rivatuner and if anybody can find a way not to lower the performance.
