Black Screen on Desktop PC

Got up this morning and found my PC locked up with a black screen. Had to unplug it to reboot. My wife logged in and started a browser but in 5 minuets it froze again with a black screen. After the third time I shut it down and opened it up. Turned it on and checked fans and heat sinks. The CPU heat sink was dusty and warm so I pulled it off and blew out the dust. The thermal paste was pretty old and dried so I cleaned the CPU and heat sink and put on some new paste. Let it run for 30min then tried some RvS (off line) for another 30min.
