Blue Screen of Death - Windows Vista. How can I find the source?

Question

My Windows Vista computer has recently been crashing quite a bit.

I installed a new video card not too long ago, but I after swapping it out for my old card, I still got crashing problems. I also tried doing a system restore, to no avail. I ran a virus scan, and everything seemed clean.

After a lot of trial an error, I think it could have something to do with some startup program or service. When I start my computer while it is connected to the internet (via wireless adapter), it crashes soon after. However, when I run it in safe mode, or start with the wireless adapter disconnected, I don't have a problem. I have been disabling startup programs through windows defender one after the other, and it's almost just bare bones right now. I still get the crashing problems, and I don't know how to resolve it.

After looking up what the two BSoD errors I have gotten, both are "UNEXPECTED_KERNEL_MODE_TRAP" errors that are caused by a "Double Fault" (whatever that is)

specifically: 0x0000007F (0x00000008, 0x803D3130, 0x00000000, 0x00000000) and
0x0000007F (0x00000008, 0x80157000, 0x00000000, 0x00000000)

Can anyone shed some light on this and help me resolve this issue?

Answer 1

Resolving the Problem



Debugging: Always begin with the !analyze debugger extension.



If this extension is not sufficient, use the kv (Display Stack Backtrace) debugger command.



If kv shows a taskGate, use the .tss (Display Task State Segment) command on the part before the colon.

If kv shows a trap frame, use the .trap (Display Trap Frame) command to format the frame.

Otherwise, use the .trap (Display Trap Frame) command on the appropriate frame. (On x86-based platforms, this frame is associated with the procedure NT!KiTrap.)

After using one of these commands, use kv again to display the new stack.



Troubleshooting: If you recently added hardware to the computer, remove it to see if the error recurs. If existing hardware has failed, remove or replace the faulty component. Run hardware diagnostics that the system manufacturer supplies to determine which hardware component failed.



The memory scanner is especially important. Faulty or mismatched memory can cause this bug check. For more informaiton about these procedures, see the owner's manual for your computer. Check that all adapter cards in the computer are properly seated. Use an ink eraser or an electrical contact treatment, available at electronics supply stores, to ensure adapter card contacts are clean.



If the error appears on a newly installed system, check the availability of updates for the BIOS, the SCSI controller, or network cards. These kind of updates are typically available on the Web site or BBS of the hardware manufacturer.



Confirm that all hard disk drives, hard disk controllers, and SCSI adapters are listed in the Microsoft Windows Marketplace Tested Products List.



If the error occurred after the installation of a new or updated device driver, you should remove or replace the driver. If, under this circumstance, the error occurs during the startup sequence and the system partition is formatted with NTFS, you might be able to use Safe Mode to rename or delete the faulty driver. If the driver is used as part of the system startup process in Safe Mode, you have to start the computer by using the Recovery Console in order to access the file.



Also restart your computer, and then press F8 at the character-based menu that displays the operating system choices. At the Advanced Options menu, select the Last Known Good Configuration option. This option is most effective when you add only one driver or service at a time.



Overclocking (setting the CPU to run at speeds above the rated specification) can cause this error. If you have overclocked the computer that is experiencing the error, return the CPU to the default clock speed setting.



Check the System Log in Event Viewer for additional error messages that might help identify the device or driver that is causing the error. You can also disable memory caching of the BIOS to try to resolve the problem.



If you encountered this error while upgrading to a new version of the Windows operating system, the error might be caused by a device driver, a system service, a virus scanner, or a backup tool that is incompatible with the new version. If possible, remove all third-party device drivers and system services and disable any virus scanners before you upgrade. Contact the software manufacturer to obtain updates of these tools. Also make sure that you have installed the latest Windows Service Pack.



Finally, if all the above steps do not resolve the error, take the system motherboard to a repair facility for diagnostic testing. A crack, a scratched trace, or a defective component on the motherboard can also cause this error.

Blue screen errors, or blue screen of death (BSOD) errors, are the most severe errors Windows can encounter. Since Windows can not recover from this kernel level error, a blue screen is displayed with the error details. The error details contain a STOP error code, which indicates the type of error.

There are a lot of possible causes for blue screen errors, but most of them relate to the computer hardware. The cause of a BSOD error can be a temperature problem, a timing error, a resource conflict, hardware failure, a corrupt registry, a virus or simply a device incompatibility or driver error.

In reality, the most common cause of blue screen errors is a device driver problem. Outdated, incorrect or corrupt drivers can cause the system to encounter a STOP error, resulting in the BSOD.So the easiest way to try and fix a blue screen error is to reinstall and update your system’s device drivers. This will ensure that all driver bugs are fixed and that all hardware has the correct driver. http://best-way-to-improve-pc-performance.com Scan your computer for free now!

Answer 4

"Double fault" sounds like two faults (hardware error conditions, usually) are occurring at the same time. Although the operating system may be programmed to handle them all if they occur in isolation, handling all possible combinations of faults may be too broad and complicated to attempt.



In other words, this sounds like a hardware problem. Bad RAM, possibly. Might be time to take it to the shop.



Hope that helps.

Answer 5

Restart your computer. If it doesn't work, maybe some of your drivers are corrupted.
