This Dell latitude D610 has ran fine for a while. End user was browsing internet doing research and had some viruses come in. 2 Droppers were the main problems...and they have all been removed along with any other detections. I used Kaspersky, Trend Micro, SpyBot and Ad Aware. I have been getting a BSOD which is what made me scan in the first place of Stop: 0x000021a Fatal System Error 0x00000000 (0x00000000 0x00000000). Everything I have looked at including the minidump points to log on issues. I replaced the vaue in winlogon in Local Machine/Software/Microsoft/WindowsNT/Current Version/Winlogon which was NWGina.dll (Novell Client) to MSGINA.dll in hopes of a returning desktop. Nothing, still same issue. Can't boot to Safe Mode, Nor Last Known Good. All give same screen. Right now I can access the registry on my local machine to make changes, but I'm stuck and not sure where to go next. Any help would be greatly apreciated.
