In my cases, the problem usually showed by not booting into anything 
useful. Since you have remote desktop, consider checking the event log.

I collected some information on how to setup debuggable Windows install 
media on http://www.coreboot.org/Debugging#Windows_7_USB - install media 
has different characteristics, which might help with tracking down the 
issue - or not.

For using WinDbg itself there are various blogs out there detailling 
how to use it. Feel free to add links to useful articles to the above
