I was recently given an hp pav. 6336 that wouldn't boot all the way up. A guy at work who knows a little about comp. said the sound card was bad & to replace it. When I uplugged the on board sound, it booted up fine. I went to an hp site that gave instructions on how to install a new card and proceeded. I installed the new card and restarted & windows detected and prompted for the driver and I installed the driver on the CD that came with it and restarted and it will not boot with the new card. It just starts scrolling down with the word unavailable for a few seconds and then a bunch of numbers for a few more seconds then just stops. I thought I disabled the onboard sound in BIOS but maybe not. Any suggestions?
