I was searching google and ran into a post that is exactly the same issue I am having.
When I first boot my Pc in the morning it will lockup requiring me to do a hard shutdown but after I do that it does not freeze again.
It only freezes when I first boot into Windows Vista 64... well about 5 minutes after being in windows from a cold boot it freezes
Looked into updates logs and nothing there that points to my ongoing issue.
I do see others with this issue does anyone know the cause of this?
It appears to be a new issue that is going around. I did upgrade recently ran memtest and heat checks everything is fine even uninstalled my AV to make sure it still does the morning lockup.
Anyone that may know please let me know what you have found or what was done to resolve this issue.
Normally if a hardware/software issue it will lock randomly off and on but this only locks when starting up froma cold boot.
