So recently, I've developed a problem where, more often then not, when I wake my Win 7, 64-bit PC out of sleep (note: not hibernation, my desktop doesn't have this feature), the machine doesn't wake properly into it's pre-sleep state, but rather stalls for a second, then reboots. Obviously, it's crashing upon waking up, but the trouble is, I can't seem to get a clue as to what's causing it.
I have software called "WhoCrashed", which is normally pretty good at sniffing out OS-crash causes, by examining the logs in C:Windows\Minidump and C:\Windows\memory.dmp except in these recent cases, whatever is causing the crash isn't leaving any logs behind. At least, none that I can find.
There are also no recent entries in my general program crash dump folder.
Any idea on how I can track what's going on?
