I bought a dq77kb mainboard and I cannot get to show information on a display.
Also the keyboard numlock led does not light up.
The processor is in the compatible procs list
its a i3-3220T processor. The cpu fan start to run. I have a headset plugged in and I do not hear any beeps
When I remove the memory I hear the 3 beeps.
I can't go to the bios as I can see anything. It appears the usb ports don't get power.
I would try a bios upgrade if I could, but it doesn't get to that stage. So no POST either. Tried clear CMOS with power cable dettached, doesn't help
All of this has also been performed out of the chassis with only one memory card in place, no connections but the power switch. It starts running it gives no unusual led activity and no beeps.
The processor is compatible and I don't have any other processors.
The power is connected externally and it has 90 Watts. It boots up an hp laptop nicely with no issues.
I followed all the troubleshooting steps but don't know what else there is I can do.
