This just started a few days ago. When my PC goes to sleep, I hear the hardware disconnect and reconnect sound and then to wake my PC up I have to ctrl alt del. I disconnected my external HDD just in case that was the problem but I don't know if it is. I haven't put the PC to sleep yet.
How should I go about isolating the hardware issue if in fact it is a hardware issue? Should I disconnect each USB device individually and put it to sleep?
