Windows ultimate 64 installed, but does not appear to be windows. Hangs on resume and sometimes fresh startup at the HP logo before windows. Drivelock is turned off in bios.

Hi

you could go to www.hp.com go to support/downloads give your make model and operating system then scroll down and look for another audio driver and download it

windows will probably ask you to restart once it is installed

hopefully this will sort it for you

or go here and download a driver both are good drivers
