lock ups

[mystic demon]

Im having some trouble running everest or speedfan. With speedfan it'll lockup before its finished loading and everything will stop responding and i am forced to restart. Everest ran however but wouldnt detect temps and eventually my system locked up. I just built this system yesterday and let prime 95 run for 4-5 hours with no errors. I plan to run it again for longer tonight. Is there any reason for speedfan causing my system to lock up just moments ago firefox caused an error and closed. I played condition zero for 2-3 hours straight today with no problems so all help is welcome. This being my first build i dont want to have alot of problems.
