MCP61PM-HM Motherboard - Startup Issue

Hello,

I'm reconnecting my system on the Cooler Master HAF 932 tower. I've reconnected each hard drive (I have two, one for the system at 10,000 RPM and the other for files at 7,200 RPM) to the same SATA ports as before on my motherboard. But at startup, it seems like the motherboard is looping, I have no video signal, and I can't even access the BIOS. There's no beep; I've double-checked all the connections... nothing works

System:
MB: MCP61PM-HM (nettle)
CPU: AMD Athlon 64 X2 Dual Core Processor 4400+ 2.3GHz
GPU: Asus EN7900GS Top
RAM: 2*512MB + 2*1024MB Kingston HyperX at 667 DDR2

My old tower was an HP Pavilion. I purchased the configuration (except for the graphics card that I added) directly from HP.
I don't know if it's my motherboard that is faulty or something else...

Can you help me?
I look forward to your responses and/or suggestions

    Hello,
    I want to make sure I understand correctly:
    you moved all your HP setup (motherboard MCP61PM-HM + processor + RAM + HDD into a HAF 932 case, and the PC doesn't start, is that correct?
    Did you properly connect the front panel cables from the new case to your motherboard?

    You understood well
    I had a couple of issues with the front button connections at first, but now it's fine.

    I think I found the problem. Since I have a 450W power supply, before, in the old case, there was only 1 fan for the CPU and 1 for the chassis.

    Putting it in the HAF 932, (especially with a fan controller because there are only 2 3-pin connectors on the motherboard), the voltage would have been too high and the power supply could have blown. This would explain why my system is boot looping...

    I don't know any other way...

    Thanks for your reply.

    You mean your power supply would have failed because of the giant fans of the HAF932?
    That's very unlikely, and I'll explain why
    The information provided on these fans shows that they consume less than 5W each:

    So that's 20W in total: impossible for any power supply to fail, even a 'no name' one
    I tend to think it's more likely an issue with the wiring of the front buttons...

    Actually, I connected the four to a fan controller:
    http://www.digitec.ch/ProdukteDetails2.aspx?Reiter=Details&Artikel=167799
    the power supply of this controller only has two small wires that turn into a molex on the power supply.

    so 20w on two small wires, could that burn the power supply in addition to the voltage that might be too high... I'm not too sure...

    otherwise, what could go wrong?
    I thought it was the motherboard that had failed.....
