Windows 7: BSOD at user login screen with error 0x000000c4

BSOD at user login screen with error 0x000000c4

Hi everybody,

I'd like to request some help for solving my BSOD problem. It happens after I enter my login credentials at the user login screen. Sometimes I don't even have time to type them in, and the BSOD happens.

The following is an outline of events in the past few days. Hopefully it can help.
  • It has been a very long time since I installed new hardware. I believe the last one was the graphics card, which was installed last year. I have not installed any new programs in the last two days.
  • Yesterday, I was playing a video game and suddenly the screen froze and the audio started buzzing. I restarted the computer and was greeted with a dialog "Windos has recovered from an unexpected shutdown."
  • On that next restart, I was streaming some videos and once again the video stopped. This was the second BSOD in a day.
  • Today, I could not get into Windows any more because of the BSOD at the login screen.

I have accomplished the System Specs form in my profile, and have attached the log information from DM Log Collector in the post. In addition, I am posting the following basic troubleshooting steps I have already performed. Hope it helps.
  • I removed my PCI wireless card. A BSOD still happens.
  • I removed my graphics card from its slot. The BSOD still happens.
  • I performed a System Restore to a restore point last week, before the BSODs began. The BSOD still happens.
  • Logging in to safe mode does not trigger a BSOD.
  • Logging in to an alternative OS installed (Fedora 16) does not show any sign of critical errors, as far as I can see. (Not very experienced with any Linux distros however.) I'm not sure but perhaps this rules out a bad RAM chip.

Thank you for reading. Your help would be very much appreciated.

EDIT: I managed to stop the BSODs by disabling Driver Verifier (I'm not exactly sure why it was set to on). I don't know if there is still an underlying reason for the verifier failures though.

Welcome to the forum.

A "stop 0x124" is fundamentally different to many other types of bluescreens because it stems from a hardware complaint. Stop 0x124 minidumps contain very little practical information, and it is therefore necessary to approach the problem as a case of hardware in an unknown state of distress.
