Thank you, cluberti. You're a really nice guy. Yes, you're right, it could be my driver or antivirus software's problem which I still need to find out. I should have already installed the KB934611 hotfix,because the Vista had autoupdated to SP1. Now today even when I change my IP Address which happened to cause a IP adress collision with another PC, the BSOD come out again. And this time it seems not related to the "tdx.sys" file. I tried to find what happened, but actually the windbg showed series of code which I barely know, here it is: IRQL_NOT_LESS_OR_EQUAL (a) An attempt was made to access a pageable (or completely invalid) address at an interrupt request level (IRQL) that is too high. This is usually caused by drivers using improper addresses. If a kernel debugger is available get the stack backtrace.

Alway when I transferring files from another PC through a router, BSOD occurs. It really bothers me a lot. The BSOD shows some "tdx.sys" driver failed. But there are not too many information about this file failure on the internet. Does anyone know what leads this problem? I really appreciate your help! I also attached the minidump file. I hope it may offer a little help. Mini060608_01.rar
