Can anyone here please tell me what is the reason its crashing everyday at the same time? Please help.

Before I could provide any reason or its solution I would like to know whether you are using Symantec. Is it installed on your system? Until you reply back, meanwhile also check this Symantec knowledbase http://service1.symantec.com/SUPPORT...pen&dtype=corp

Yes Troy, we are using Symantec with Roxio. Is all that in the bugcheck string? What should I do now?

No, I happened upon the Symantec link in a Google search for: 0x0000008e.
