PCH Poison Interrupt is possibly a hardware problem on Debian Linux

I cannot use the Debian Wheezy machine and the only error message is "PCH Poison Interrupt". I can only repeatedly press Ctrl + Alt + F2, and then Ctrl + Alt + Del to restart the machine. I cannot do other things.

After trying several times, I have found the solution to this problem.

In my case, this is a hardware problem. The VGA cable is broken inside. This cable looks good on the surface, but it is broken inside. In addition, the VGA cable is loosely connected to the machine.

The solution is replacing the broken wire with a new one.

I have used the DVI cable instead. I have properly connected this cable. I can start the machine now. The problem is solved.
