Thank you for posting this question.
Unfortunately, this problem description does not provide enough information to diagnose the problem. I hope you can help provide answers to the following questions.
Is it correct that you installed Autodesk Design Review 2010 and DWG True View 2009, and then the machine reboots automatically every time you try to import DWG files?
Do you find the same behavior when using DWG True View to open DWG files?
Do you experience this problem with ALL DWG files or only certain files?
I will try to provide some help after I better understand the problem.
Please upload an example of such a file here and post back with the link for me to investigate.
Please let me know after the sample file has been uploaded.
