E8500
ati4850
gigabyte mobo
4g corsair
pcp + c 610w
640g 7200rpm WD hdd
big arse pcu cooler

I just got done assembling my first comp with the parts that many of you were so kind to help me pic out but when I power up the unit all the lights/fans and mobo leds come up but only stays on for apx 8 seconds, shuts off for 8 seconds and continues this on off on off on off cycle. I have checked connectors and everything appears tight and correct.

Where do I start?

Getting four leds on mobo (red, orange, green, green).
One red led on GPU
all leds and fans *including cooler* come on and spin.
Optical drive led comes on.
4 pin power connector on mobo connected.
Intermittenly only stays on for apx 2 seconds and shuts off for 8. More consistantly 8 on 8 off...

I'd check to make sure the cooler is on correctly. Pull it off, check the footprint of the thermal grease, reattach it.
