So I just purchased a CX600M psu and GA-Z87-HD3 mobo with an I5 and 8 gb of crucial ddr3 ram. When I boot the computer, the case fan lights up for a second or two, the gpu fans turns on and the psu fan turns on, then the case and gpu fan both immediately turn off. the psu fan stays on. then the fans turn back on and back off agian. the cpu fan does not ever spin.

We need more information, please list the model of your processor, graphics card and memory chips. I would the graphics card and see what happens. Does the system make any beeping noises, if it has a speaker to connect make sure its connected to the header on the motherboard.

Core i5 4670K, MSI R7770-PMD1GD5, and Ballistix Sport 8GB DDR3-1600. It does not make any beeping noises, just turns on momentarily and then turns back off. I've tried moving the ram around, and ive double checked all the connections.

You did say you have both the 8 pin power connector and the 24 pin power connectors attached correct?

As far as I know yes, the 24 pin is in correctly, the other 8 pin connector from the psu is gonig into the atx 8 pin port in the top left of the board.

I did not try with one stick of ram, I did disconnect the gpu and had no change.

Could be a faulty motherboard, the components all appear to be compatible. If there are no beep codes it means it's not even starting to post. Reset your cmos and then reseat all your components, cpu, memory etc.

just put in a pc power and cooling silencer 760 watt psu and same thing happened. tried one ram, in all 4 slots, same thing. tried kingston hyper x ram, same thing happened. the psu fan runs continuously, the cpu fan does not turn on at all and the case fans turn on then off repeatedly.

also, does reseting the cmos void the warranty?

No it will not void the warranty, although at this point I am thinking it's your motherboard.

you test the gpu with only the power cable unplug you have to remove her from the board to use the onboard video for testing .
