OK, let me re-cap. Guided by MTU recommendations, I purchased a Toshiba Laptop with Nvidia graphics card and bought the Hoster software so that I could run my twice weekly karaoke show using state-of-the-art technology. It has never operated as expected despite the fact that I have downloaded all windows updates, Nvidia drivers etc and despite the fact that I have followed the changes in settings recommended by MTU in their manual even tho they were obviously printed for Win 2000/XP users etc. I've had my laptop system checked over by the Toshiba people under warranty and all is operating as it should.

Putting it simply, the problem is that when I run the "Hoster" software, it will at some stage just simply go blank whilst is it playing a song and the music will stop. I then move the mouse which causes the screen to re-activate and a blanked-out replica of the Hoster screen re-appears over the desktop screen and an error message appears reading "Hoster Application has stopped working", followed by the words " A problem caused the program to stop working correctly. Windows will close the progra m and notify you if a solution is available." I then close this window and investigate further but so far Windows has failed to find that solution. On advice received from other thread contributors I've just studied Task Manager during a couple of such failures. On the first occasion, the CPU usage spiked to 36% but there was no real difference in Memory. On the second failure there was no discernible difference in either reading............so there you have it. I appreciate all input but so far it seems I've invested in a "lemon". Apologies for rambling on. Can anyone help further. My second computer is a Pentium 4 desktop running XP. Guess what?? No problems with that one so far, touch wood.
