There should be (2) power connectors labeled P8 & P9. From the left 
edge of the power connector with the connector facing you with the
pin side unexposed, P8 goes first followed by P9. Check the rating
of your power supply -0 it should be at least 200W. Best way to 
check a power supply is to use a multimeter, and look at the readings
off of one of the drive power cables. On most power connectors, 
black is ground, yellow is +5VDC, and red is +12VDC. You can accept
values for anything up to +/- 0.5VDC on the power supply - anything
else than that, you could be runnning into problems.
 
Also make sure that there's nothing "random" rolling on the bottom of
the case between the bottom and the solder side of your motherboard.
Also ensure that your power supply is properly grounded via it's
power cable to the wall.
