First time to post, been a lurker for many moons.
Here's the problem.
I have a Dell Inspiron 531 that has the 7B BSOD. First I rec'd the computer with the complaint that it wouldn't connect to a network through the NIC card. It just sat there with "Acquiring Network Address". I ran CCleaner to clean it up a bit. MBAM found several problems, but fixed them. I installed Avast 5 with the latest vpsupd file (definitions). Configured it to run a boot-time scan. It found several items and deleted them. I turned it off and inserted a NIC card to rule out the onboard NIC card. Booted up and Avast started complaining about atapi.sys while XP was trying to install the new card. I couldn't break out of the cycle. I looked up the problem online and ran GMER. GMER found atapi.sys had been infected with win.Fluereon(something) [sorry, this is from memory]. I killed the file with GMER.
and then I rebooted and hit the 7B BSOD.
I copied a virgin copy of atapi.sys to the drivers and dllcache subdirectories of system32 using MiniXP from Hiren's Boot CD 10.1. I ran chkdsk /f using Hiren's Boot CD 10.1 and fixed several errors. Finally I ran bootfix and rewrote the MBR.
Reboot still gives me a 7B BSOD.
The disk is usable and can be seen both in Linux and Hiren Boot CD's Mini XP. No Safe Mode, either.
