Homebuilt system powers on, but no beeps, no display, nothing.

Hi there, I am building a PC and am having some issues. The story is: I bought:
MSI P67A-c43 (b3) Motherboard,
Intel Core i5 3570K CPU,
Corsair Vengeance 16GB (2X8GB) RAM,
AMD Radeon HD 4870 GPU,
A KINGWIN 650W PSU (Can't find the exact name; no box. If desperately needed, I can find it),
And a 500GB Seagate HDD.

I bought all of these components, put them together (minus the hard drive – wanted to test POST), and when it powered on, the "4-light power phase" lights came on: first one light, then immediately all 4 lights came on. I heard a 4 long beep code. We researched that and found out that either the motherboard was bad, or the BIOS didn't support the CPU, which was very likely. The CPU fan started running, as did the GPU fan (The CPU fan kinda does a sort of 10 degree rotation twice, then starts spinning normally). After a second or two of the CPU fan running normally, the machine immediately shuts off, lights, fans, everything. And after a few more seconds, repeats the process over for forever. My dad and I looked into this, and discovered that the BIOS version did not support my Ivy Bridge processor, so we ordered an Intel Celeron G440 processor (the cheapest Sandy Bridge one that my processor officially supported), put it into the machine, and booted it up. The CPU fan does the same thing; however, it doesn't shut down. The lights stay on, the fans keep spinning, but I get NO BEEPS, NO DISPLAY, nothing. Even when I remove all the RAM, rearrange it, etc., and take out the GPU, all of that, I get no beeps or display (I know the GPU gives display via DVI to VGA, but you know what I mean). I tried all that I could – resetting CMOS, swapping CPUs, swapping RAM, EVERYTHING. Nothing is getting me a display. The monitor works, and so do the other monitors I've tried. Everything appears to be seated and connected properly, so what could be wrong? Could my motherboard REALLY be bad? I really hope I can get everything running, because I've been dying to play some games! Thanks so much! OH! Another detail: when I click the power button that's connected to the power switch port, I can't completely turn off the machine; it only reboots, if that helps anything. Thanks!

- Alex


Added: Just so everyone knows, my 3570K is officially supported by my motherboard.

You may have burnt out the mb with ib CPU. New mb don't have speakers on them unless the case come with them. Look at the bios lable on the mb make sure it at a rev to post your cheap CPU needs 1d bios there are older bios. If I was you I return the mb and CPU and pick up a h77 micro atx that are under 100.

If I had to guess it would be that you burnt out your motherboard like smorizio said. If you have one on hand, try breadboarding on another Motherboard and test all your parts. Also it could be the PSU. I say that because of the way you described your cpu fans and the way it shutdown. Your PSU could be bad, try using another one from another pc and take out your GPU and use your onboard graphics. If I were you, I'd find another Motherboard that is compatible with all your parts and buy it to test, if it has the same issues return it, that way it eliminates the possibilty of it being the motherboard and you can start narrowing it down.

But why would my 3570K Ivy Bridge processor, that is supported, burn out the motherboard?

You said it wasn't supported in your description. If it is supported then that wouldnt have been an issue. I think you should try another power supply.

Do you really think it's the power supply, and not the motherboard? If so, what would be the reasoning?

ThEre Only two x6x chipset that I know that will do ib CPU. The updated h61 chipset and the older x68 with a bios update. The x7x chipset and ib bios should be plug it in and it post fine.

I cant guarantee it but its a possibility just from the way you described your problem. I think it either has to be a bad motherboard or a bad PSU. Im leaning towards PSU because of your description, but if you have an extra one on hand like I said exchange them out and see what kind of results you get. Make sure you boot with the proper amount of hardware that the other PSU can handle. If your results are the same, I'd say its your motherboard.

And your CPU is compatible seeing that its a LGA 1150 and your motherboard supports that.
