That means that a 'kernel panic' has occurred.  It probably means you
have a hardware problem.
Hold the shift key down during boot and it should show you a menu that
includes a RAM test option.  Select that with arrow buttons and hit
enter.  Leave it running for a number of hours and see if it happens
then, or if it shows any errors.  If so then it is a hardware problem.
It could be overheating, in which case opening the case and cleaning
the dust out and making sure the fans are functioning may help.  Or it
could be the power supply.

Before doing anything else make sure that you have backups of
everything important on the PC in case it breaks completely.
