Computer won't turn on after new cooling unit

[AhhNickk]

Hi guys,

Today I just installed a new water cooling unit from Corsair (H100) I have everything set up right but right now my computer won't start. When I press the power button all the lights comes on, the motherboard light, fan turns on (CPU Cooler fan, Front and back fan, PSU fan and its lights) but it stopped right after that. Please help.

Edit:

AMD FX 8350
MSI 970A-G63 AM3+

Are you certain that it is connected to the motherboard? A lot of motherboards will not boot the PC when a CPU cooler is not recognized because they aim to prevent overheating to the CPU.

Yes I'm sure that it is connected to the mobo, there is a Sata power connector but I have 4 pin molex on the PSU so I bought a 4 pin molex to connect the Sata to the 4 pin molex on the psu. and the other 4 pin right into the mobo. I also tried the stock cooler and it does the same thing...

You're saying you have the same issue when you use the stock cooler as well? If you are installing and wiring both cooling units correctly, you may have somehow damaged a part when installing your new cooling unit, possibly your motherboard. I would see if you could get an expert to take a look at it and see if you can either get a repair or consultation of some kind. However, if your fans stay on in the PC it could be a problem with the video card as well. I would get that checked as well.
