|this is in reference to where people cant hibernate more than once in one session....|
i couldnt reply to the ealier thread as it is closed. i have been having the same problem for a month. finally found the soution so thought will post it here.
first u need to search for unsigned drivers. refer article http://support.micorsoft.com/kbid=3...
after getting the unsigned files list. check which program refers to these drivers. for me it was nero 6 and partition magic 8.
uninstall the programs and delete the related drivers.
