BSOD c00021a Fatal Error works one time then again.. I have this dell XPS GEN4 with Win XP pro. Got one of those nasty Antivirus 2010 and tried to take it out restarting in Safe Mode...but I constantly get this BSOD in safe mode and normal mode too. I tried to use XP original disk and Reinstall system with: - Press Enter to Install new copy of win - Looking for prexiting win installation - found WIn XP - Esc to install new one/ R to repair existing on - Pressed R After I repair the installation the computer boots ONE TIME only and I can go to my desktop. Malwarebytes will shut down when opened so I cant take the Antivirus 2010 out. If I restart computer in safe mode...I get the BSOD and it starts to give me BSOD every time. I know it has something to do with gina.dll registry. My gina.dll registry key is missing after reinstall. REALLY appreciate! Here is my minidump.
