OK here is the story in a nutshell. I recently got a clients laptop which was infected with malware. I decided to do a fresh install. Reformatted the drive and installed XP Home. All the drivers worked at first, including the SOUND/AUDIO. Speakers played sound just fine. I went on updating Windows through Windows Update, as the disc I have is an OEM/Retail with only SP2. Downloaded all updates fine including SP3. Noticed Windows Update had hardware driver updates available including the audio drivers. Did the updates and everything seemed to work fine. I then noticed after I had installed Office 2000 and other software, that the sound/volume icon was no longer showing up in taskbar near the time. Looked into the device manager and the SoundMAX Integrated driver had a explanation mark near it. So I found the correct audio drivers again from the actual computer manufactures site. (Compaq) Downloaded and installed. After the required restart, it kept doing a BSoD and restarting over and over. So I disabled the auto-restart feature to see what the culprit was and it said that the sysaudio.sys file was not working correctly. It boots fine in safe mode. I couldn't get the sound driver to ever work since. I have tried using 2 different source XP Home OEM CD's so far. Now after brand new install of Windows, it goes STRAIGHT to the BSoD after trying to boot for the first time. Could the soundcard on this laptop be just shot?? I am getting very frustrated with this problem, as the audio drivers were working FINE on the first install of Windows.. I can boot into safe mode fine as it doesn't load that default sysaudio.sys driver. I disable the driver that Windows finds at first, which isn't the correct driver. Windows finds the audio as a VIA 97 AC Codec. I am at the tipping point with this laptop. The client is waiting currently for the laptop, which I told him it was ready Yesterday, before I noticed the sound/BSoD issue.
The Laptop is a Compaq Presario 725US
it has 240MB of RAM
AMD Athlon 4 1600+ 837Mhz (which sometimes shows as diff values 400, 600, and 800Mhz)
Any ideas??? I can boot fine into Windows with the current audio drivers that Windows assigns set to disabled. The client obviously wants some sound though. Any ideas would be great. I am even giving an Windows XP Pro disc a try, but don't want to have to go through the trouble of installing another OS and it do the SAME thing on me..
I have attached the minidump file that was compiled after the BSoD.
