Hi,
Thank you for the post.
Please understand that to troubleshoot the blue screen issues, we usually need to perform debugging. However, in this forum, we do not provide debugging support. If you would like to perform debugging, please contact Microsoft Customer Support Service (CSS).
To obtain the phone numbers for specific technology request, please refer to the website listed below:
http://support.microsoft.com/default.aspx?scid=fh;EN-US;PHONENUMBERS
If you are outside the US, please refer to http://support.microsoft.com for regional support phone numbers.
Having said that, I'd still like to provide the following general troubleshooting steps to see if we can eliminate this problem:
Note: Please perform a complete system backup first. If any unexpected issue occurs, we can quickly restore the system to the current status.
1. Update the drivers for the motherboard and video card.
2. Scan your system to make sure that the system is virus free. If you have recently installed any software, hardware or drivers, please remove them.
3. Ensure all the hardware devices, installed device drivers, and installed applications are all compatible with Windows Vista.
4. For Compatibility information, please refer to Windows Vista Hardware Compatibility List:

5. Disable all the third party startup programs and services by using the MSConfig.exe utility shipped with Windows Vista. To use this tool, you can refer to the following Microsoft Knowledge Base article:
How to troubleshoot a problem by performing a clean boot in Windows Vista
http://support.microsoft.com/default.aspx?scid=kb;EN-US;929135
If the problem does not occur, it indicates that the problem is related to one application or service we have disabled. You may use the MSCONFIG tool again to re-enable the disabled item one by one to find out the culprit.
However, if the issue still persists, please contact Microsoft Customer Support Service (CSS) for further troubleshooting. I hope the problem will be resolved soon. Thanks!
