chassis intruded fatal error system halted
P5Q-E com Chassis intrusion
What is your question, without that I can only go on assumptions. My assumption is you want to know what it means, basically there is a pressure switch (or other push activated mechanism) in your case that sends a signal when its been released. Typically it is released when your case is opened although it may have come loose. Check it to make sure it is in place and only operate your computer when the case is closed. If you wish to operate your computer when it is opened then locate the driver for the switch, remove the driver and then remove the switch.
