I have a strange problem that's been happening with a PC of mine, an HP desktop running Windows 7 32-bit.
In the past couple months, the PC will occasionally go into what appears to be a hard drive shut-off mode or a suspended state. The power is still on, fans a-spinning, but the monitor is off (not a screen-saver, completely off).
Moving the mouse, pressing keys on the keyboard, and pressing the power button on the machine have no effect. The PC will not wake.
I use LogMeIn on this machine, and in my web interface I can also see that it is not connected to the internet nor the local network. Nothing in LogMeIn settings can cause this behavior. I'm the only user with access.
It is a clean Windows install with only LogMeIn Pro, and Tight VNC server. Nothing else has been installed. Windows Update is set to Download Only (let me choose to install).
This problem has been occuring roughly once per week.
What I've Tried So Far
In Power settings, I've set every timer to Never. Hard disk shutoff, monitor, sleep are all set to not ever happen.
I've tried sending WOL packets through LogMeIn, but it is not connected to the local network, so no dice.
The only way I can resolve this problem as of now is doing a hard shutdown and boot it back up.
