CRIKEY thank you excellent result.its a definate bad result as well bad luck 4 nvidia needs reinstall, standard dual chanel controller, lucent win modem, SM bus, PCI audio drive, Standard universal PCI to USB host x 3, Multimedia audio controller< plug and play monitor, printer port, samtron 76e/77e ALL ITEMS need hospitalisation. so i will go and compare what the hardware tree has to disable.Originally the tree did not have some of these items. which then leads me 2 wonder if i disable and enable across the tree will this cause any futher probs. my modem thats operating is a motorola, and i think samtron is a cpu screen? where as my dell is operating, therefore would your better judgement allow operations to disable those that are not in operation or would the scan pick up this problem unsure what the stats are but the original tree was fully functionl .Bar the sm bus, what to do block or not?? thanx
