I’ve got something really weird happening. My computer was custom built with an Asus P4P800-E motherboard. It’s run great for the past 20 months. But in the last couple of months I’ve noticed something bizarre.
In the middle of the night, while the computer is turned off the CPU and case fans start all by themselves. They’ll run for a while and then turn themselves off and then repeat the cycle.
The LED lights on the front flash while this is happening. Also, since it’s connected to a 4 port KVM switch (via USB) it causes the KVM switch to beep and flash the light for this computer.
One more thing. It seems to be triggered at about the same time each morning (approx 4AM).
Anyone have any ideas about what could be causing this? It’s driving me nuts.
