The computer does not start, the speaker clicks, and the fan twitches. What could be the problem?

Good day to all!
I bought myself components for the New Year, assembled a computer that refused to work ... The configuration is this:
MB : Gigabyte H77-DS3H rev1.1
Processor: Intel Core i5 3550
Video card: Gigabyte GTX660 2048mb
PSU: Chieftec CTB-650S 650W
Memory: Kingston 4Gb x2 1333Mhz 1.5V
The computer, as I said, does not start. The processor fan (boxed by Intel) twitches slightly and does not spin at all (connected to CPU_FAN). Case fans spin without problems (SYS_FAN).
The speaker makes clicking sounds, an infinite number of times. The hard drive also clicks in the same way (the sound is like when it starts), its light blinks.
Such a 6th feeling and the feeling that the computer reboots many times, constantly and often (judging by the hard restart).
Nothing is displayed on the monitor - even though it is connected to the video card, even though the video card is disabled and the monitor is connected to the motherboard. One result - the monitor writes "No signal".
What I tried: to pull out all the RAM - the speaker began to squeak frequently and briefly thirty times, then silence for 5 seconds, then squeaks again.
Putting one stick of memory into different slots did not help.
Reinstalling the processor in the socket did not help (I checked the socket and processor contacts at the same time - they are all intact, everything is fine)
Starting the system without a case (you never know short) - did not help.
Having launched the PSU without a motherboard (by connecting PW_ON and COM), I checked all the voltages on the lines - they correspond with some errors.
Help, please, what could be the matter?

First of all, check by replacing the power supply. If it doesn’t help, and with everything removed (except for the power supply and processor) it doesn’t start, then, most likely, the mother is to be replaced.

Excuse me, but have you connected the cable from the power supply with a 4-pin connector to power the processor to the motherboard? Because the symptoms when this cable is not connected are approximately the same as you describe. Sorry, of course, if connected, but anything can happen.

Often observed similar behavior. As a rule, as already mentioned, with fully functional equipment, the problem may be in the BIOS and flashing may well help. By the way, resetting the CMOS settings can also help.
Also try to start with a minimum of components - motherboard, RAM, integrated video card.

This mother has video outputs, and the CPU has Intel graphics. Accordingly, I propose to separate the last non-vital part from the system, and make sure that everything works.
And then vidyuhu in service.
(I had very similar symptoms, only there with smoke and special effects, and the map was a couple of years old)

There was a similar joke, though even on the previous generation, the problem was that the BIOS installed in the motherboard did not know the percentage. It was cured only by installing an older processor (fortunately it was at hand), after which I updated the BIOS, and after that the new processor worked.
In general, if there is an opportunity, try to install an older model of the processor, but if there is no other processor at hand, then to the service., Well, or if another 14 days have not passed, then to the store to change, so faster than in the service.

Are you sure all components are compatible? Is the memory certified for this board? Is the CPU supported by your BIOS version? Also check the 4 pin CPU power connector.

My guess is that the problem is with the power supply. Screw clicks most likely mean a power drawdown. Well, in general, the situation is something classic: since there are no other diagnostic methods, it remains only to change the components one by one, starting with the most minimal configuration. Since the system beeps without memory, it means that at least the processor is working (i.e. the BIOS has started). Perhaps the memory is broken, or not compatible in some way.
Once upon a time I had such a situation: also recently purchased hardware did not start. I took everything to the seller, they replaced the memory and everything started up. But what is interesting: you could leave the old memory, but replace the power supply, then everything started up too! It turned out that the PSU installed in the case had some ripples, which did not like the NO NAME memory. When installing Samsung memory, everything worked with a pulsating PSU!
In general, you bought all this, paid money, and, in theory, sorting out the jambs of iron is not your concern. It is necessary to collect all this in an armful and take it to the technicians of the seller. Let them spread this whole thing on the table and run it. They have a lot of different hardware at hand, it’s easier for them to test. Although, they may, having found a problem, try to blame you for breaking it, but let's hope that this will not happen.

Follow the classic scheme: disconnect everything from the motherboard (including the processor and RAM), leaving only the power supply and the power button (you can connect the processor cooler fan to see if the power supply starts up).
Try to turn it on - if it starts, put a percent and run it again. If it doesn't start, try changing the power supply to a known good one. If it didn’t work, and so - the mother in the service.

1. Does your processor have a graphics core on board?
If the processor does not have a graph. cores on board, then the "on-board" video will not work, and when buying a motherboard with vga / dvi / hdmi, you buy only the means of outputting the information that will be generated by the graphics core built into the processor.
This should be carefully checked when buying a motherboard and processor.
It is also possible that your PSU may not be enough to feed all this iron.

Check connection. A couple of months ago I met a sistemnik with similar symptoms. The reason was in the power supply of the case cooler (it was short), after the cooler was turned off, it worked like a clock.
