My motherboard does a POST beep code for virtual mode exception error (7). Because of this I get no display. But if I use a graphics card everything works fine. But another issues it seems that the motherboard is going into a weird hibernation mode when asked to shut down. The computer does shut down the LEDs go off and the display goers off but the fans inside are spinning so its like it went to sleep instead of switching off. Any ideas what may connect these two problems? I already cleaned the motherboard and reset the BIOS.
