When i power on computer then after few seconds or minutes immediately turns off

I need help please

Here is video of my problem:
 
First thing I would do is unplug everything from the mother board including any daughter cards such as graphics etc. Hopefully you have on board graphics so plug your monitor into that and see if your computer runs the power on self test or POST. If it does then your mother board and power supply are okay this should also check your RAM modules. Next, if it still doesn't boot then make sure the computer is switched off and unplug the RAM modules and plug them back in making sure that they are seated properly. If it still doesn't work then it's possibly the power supply or the motherboard. Unless you have test equipment these cannot be tested easily and substitution is the easiest way to determine if either of these are faulty. Unless you have spare bits the power supply is the cheapest bit to replace first. When I say unplug everything this does include the hard drive and the cd/dvd rom drive. Your computer should do the POST without these items.
 
First thank you soo much for advices:
I unpluged everything and the problem is the same.
When i plug monitor to graphic card it works, windows loads, but computer shuts down by itself after few seconds.
I have now pluged cable from monitor to motherboard, and windows does not load, nothing loads. Only graphic card fan started spinning faster and sound of spinning is louder, after few seconds computer turns off. But i tryied to connect graphic cable to motherboard 1 week ago and it was loading only system not windows, now it does not work.
I have unpluged and pluged rams, and it is still same problem.

When i unpluged everything even CPU from mother board i broke plastic that can attach to motherboard, so then i have glued mother board and CPU FAN with glue gun, that can now attach parts.
And my CPU coller starts jingle sometimes: Immage what i glued to motherboard:

Video when i was connect graphic cable to motherboard (comp startup) :

And a week ago when computer was working about 20mins, the graphic card started heating. It was really hot.
 
You can't glue the heatsink/fan to the motherboard, you are overheating and thats why its shutting off on you. You have the blue video cable connected to the wrong video output, you have a dedicated video card and the cable needs to be plugged into that.
 
I connected blue video to motherboard for check, on the video is cable connected to motherboard for test of it working, but i have connected cable direcly to my graphic card
 
Is this a brand new build or have you been using it for some time? If you break the plastic connectors on the bottom of the heatsink, then you'll need a new one so you don't overheat. If this is a brand new build, I would suggest taking it apart and rebuilding it and making sure you have used the standoffs between motherboard and case as well.
 
I am using computer for about 7 years,
Yes i mean plastic connectors, that they attaching CPU fan and cooler with motherboard. There are 4 plastic white connectors , and i broke 3 of them so i had to glue at the bottom of connector with glue gun..
That was just happens incidently, when i trying to fix computer.

And thermal paste is old, for what is termal paste?
 
I told Ales to unplug everything from the motherboard and then power up the computer that is why he has the monitor cable in the board monitor output john. What Ales didn't do is unplug the graphics card from the motherboard before testing the motherboard.
 
You need a new heatsink/fan. You can't just glue it on there.. LoL

Buy yourself a new heatsink/fan and a tube of thermal paste.
 
Pete: Now my computer works without graphic card, i dont know how? Graphic cable is pluged to motherboard.
But problem is the same after some minutes my computer shut down..

Laquer Head: Thanks for advice
 
Okay I am assuming that everything is now disconnected from your motherboard. Your MB has on board graphics which are no where near as good as you graphics card but are adequate to run your monitor whilst testing. Anyway this could be a heat problem and if you have broken the CPU heatsink fixing lugs then the cooler will not be making an adequate contact with the CPU and that is overheating and shutting your computer down. You may well have introduced other faults now so the first thing you need to do is sort out the fan/cooler fixing problem using new thermal paste as Laquer Head has said.
 
Yes, it can be reason, i will buy new CPU fan and cooler, and is it thermal paste neccesary? And for what?
 
You need to reapply new thermal paste when putting the new heatsink on unless it has a thermal pad already on it.
 
The thermal paste helps to conduct the heat from the CPU, which can be considerable, to the heatsink. If you have a thermal pad then you will need to be careful how you separate the heatsink from the CPU. If you manage to rip the pad whilst removing the heatsink then you will need a new pad. If you buy a new heatsink and fan they usually come with a small tube of thermal paste or a pad but make sure. If there is no paste in the box then whoever you buy the heatsink from should be able provide thermal paste or a thermal pad. Whether you get a thermal pad or thermal paste ensure that you clean all the old paste or pad residue thoroughly from the top of the CPU.
 
Thank you all for helping me i replaced CPU cooler and fan, and thermal paste. Now computer works normally.

but graphic card is strange to me it is very hot.
Maybe i put to much paste on it?
Can be something wrong if there is too much paste on it?
