I keep getting the bsod, one of the reasons is driver_irql_no_less_or_equal, somethin like that, and it says afd.sys is the problem, so i read up on it, and i read that to fix it i am supposed to change the name to afd.old and restart so it will reinstall, however, when i go to change the name in safe mode, it says i do not have permission, i am the admin of the computer soi was confused, then went to properties of afd.sys and gave myself full control of the file, but once again, it said i do not have permission to do that, so how in the world do i get permission, or does anyone have any ideas about any of it, some specs are, i am running vista sp2 amd 64 5000+ with a geforce 8500 graphics card

You don't have access because the file is probably in use You should be able to rename the file from the recovery console http://support.microsoft.com/kb/307654/en-us Deli
