Hi,
Before I start I would like to say I have tried all the obvious things - take out all DIMMs and Cards, reseat CPU, RAM etc, and all the rest. Please look below for a list if my specs.

Three weeks ago I decided to upgrade my perfectly fine computer. I bought I new power supply - a Corsair CX600M. So I disconnected everything from my old power supply, took it out and exchanged it with my new one, plugged everything back in just as it had been before and... It didn't post and my motherboard speaker didn't beep, bearing in mind that my motherboard was an Asus P8H61-M R2.0. So I though huh, I must've connected something wrong so I disconnected everything and plugged it all back in. No post. Then I took my motherboard out and followed about 3 different tutorials online for building a pc (also I build this pc the first time), and surprise surprise, none of them posted either. So I thought it must be my power supply and went to connect it to another Mobo I had lying around. Two beeps. Not sure what that means but hey, they beeped. So at this point I had ruled out that it was my Mobo speaker or my PSU that had caused this. I decided, also having changed the ram unsuccessfully, that it must be my motherboard, and went out to buy an Asus H61M Series. Switched everything over to the new Mobo including my PSU, no post or beep. Switched psu's. No post. Switched ram again. No post. I have no spare CPU to check, but I don't think it's that anyway.

Does anyone have any suggestions? I will list my specs below.

CPU: Intel i5-3330
GPU 1: GeForce GTX 760
GPU 2 (neither of these showed monitor signal): GeForce 630
Motherboard 1: Asus P8H61-Mx R2.0
Motherboard 2: Asus H61 Series (can get exact model if needed)
RAM: 2x8GB Komputerbay DDR3
PSU 1: Corsair CX600M
PSU 2: some random old one

I hope this helps and any suggestions are appreciated.

Hi

Did fans start up ?
Even if nothing else happened
If not possibly power switch cables loose from motherboard

Did you follow breadboard testing ?
CPU , one ram stick, heat sink + CPU fan psu ( nothing else connected) except screen and keyboard
Use integrated graphics if possible

Best of luck

Sorry didn't mean to select best answer :p  problem isn't solved.

No cables were loose and I properly breadboarded every time.
