I need help computer won't kick on

post #1 of 11
Thread Starter 
I just recently installed a corsair hx750. After I got all my cables back in orederd and tied down. I re connected everything back to the computer and tried to power it on. When I press the power my top fan led flashes on then off. So i figured I forgot to plugg the power swith to the mobo, it was connected correctly. So I checked the 8 pin for the CPU and the 24 pin for the mobo. I have been playing with this for an hour, but can't figure it out. I would really appreciate any help here. Thanks to those who reply.

Are motherboard standoffs installed? It may be shorting.

Did you try reinstalling the old PSU to see if everything still works with that?

As Reflux said, have you tried your old PSU again? Make sure everything is connected and secure.

You need to take all of the components out and assemble the system on a work bench, outside of the case. If you still see the same behavior, then you will know something is defective or incompatible.

if your case has round raised standoffs that are molded in to the motherboard plate then make sure to cover them with electrical tape before installing the motherboard. My girlfriends computer had the exact same problem as yours.. try testing it out of the case

Thanks for the answers guys. I did try hooking up my old psu to it and it turned right on. But I looked at all the wiring and found that a cable had a some exposed spots. Replaced it and it turned right on.
