New Build Boot Up Issue

[dvanwag]

OK, so I finally built my first system (specs posted below) and when I push the Power button the system starts up for a few seconds and then turns off. I have read the sticky about things to check before posting for advice and I went down the list but cannot still for the life of me figure out what the problem is (though I will admit that I am a Noob at this). I've checked all connections, tried different electrical sockets to start up from, etc.

The only other tidbits of information that others may find useful is that (1.) after I plug the computer in there is a single blue light on the motherboard, so I dont know if that indicates issues elswhere as they're are no other lights and (2.) when I hit the power button and the computer comes to life for a few seconds all the fans seem to function fine except for the ones on the CPU cooler. Also, the LED lights on the case light up as well.

My System:

Cooler Master HAF 932 Case
Intel Core i7 920 CPU
Artic Silver 5 Thermal Compound
Cooler Master Intel Core i7 Compatible Hyper N CPU Cooler
EVGA E758 X58 Motherboard
Sapphire Radeon HD 5770
OCZ Gold 6BG DDR3 1600 RAM
Rosewill Xtreme Series 950W PSU

I greatly appreciate any and all assistance!!!!

THANKS!!!!!!

If that blue light is what I think it is, it just indicates that there is power going to the motherboard. Check and make sure ALL your connections are securely in (My friends comp had part of his 24 pin loose and it caused shutdowns a lot). Does your computer stay on or stay off after pressing the start button ?

I've triple checked all the connections, could not detect anything out of the ordinary. The computer doesnt stay on at all, I press the Power button and it begins to boot up and two seconds later it shuts off again. Mobo maybe?

Take the system down to its bare essentials. CPU, video card, single DIMM of RAM. If you still have problems you may want to set it up outside the case to see if it may be a short somewhere. Make sure you don't have any extra standoffs in a place that doesn't line up with a screw hole on the motherboard.

+1, If booting outside the case still doesn't work, you might have a bad mobo (My friend bought the same mobo and it came DOA the first time). Check your board and look for blown transistor/capacitors
