refer to line 22: Probably caused by : Mup.sys
Mup.sys deals with network UNC paths, and correlates to the BSOD's you are receiving as it may be corrupted. First try start > run > sfc /scannow > OK

if this does not resolve the issue you will want to apply a windows REPAIR install (not a windows reinstall) where only windows files are reinstalled and everything else kept intact.
see instructions for repair installation:
