the following may of some concern to you but it involves a little "housekeeping." unplug all your peripherals and unplug the cord from the back of the machine. lay the computer on its side and remove the side plate. look on the processor heat sink. this is a large square finned affair. vacuum off any dust here. the fan is fastened to the heat sink by four phillips head screws. unplug the fan and remove the fan. remove the dust on the heat sink. put the fan back and screw it down and plug it back in. what has probably happened is the dust overheated the processor and the thermal overload tripped freezing your machine. while yer in there blow out any dust you find especially around the fans and in the power supply.
