This is called a "kernel panic" (or KP for short). Nine times out of ten, KP's are a sign there is a hardware problem. The first thing to do is to give the insides a thorough clean. Do not use compressed air! Use a hand-brush and a vacuum-cleaner on low suction; the only exception is the power supply, hold the bare end of the vacuum cleaner hose over the fan-holes and use maximum suction. Unlug or remove anything that can be unplugged or removed (board cables, RAM sticks, cards) then re-assemble. If you have the original machine CDs available, dig out the Apple Hardware Test disc, boot from it, and run though the extended tests (note: full tests could take several hours to complete). Boot from another Mac OS install and use Disk Utility to check the S.M.A.R.T. status of your hard drive(s) and then use its First Aid function to repair your normal boot drive. If it finds errors it cannot fix, you will need to use Disk Warrior, by Alsoft. If you still experience KPs after all of the above, then you will have to face grim reality -- entropy has finally caught up with your machine and parts are beginning to fail. Most likely culprit will be the power supply. Second most likely culprit will be the processor daughter-board itself.
