second after it starts. And when I press the power button again in this state it does not start at all. not even for one second like it did the first time. Then I have to switch off the main power supply to the computer and switch it on again before the power button works but again the computer starts for may be one second then switches off."
I have replaced the CMOS batteries but that did not seem to help. I have also replaced the cable, plugged it into another power supply but that did not help either. I have also disconnected the cable running from the power button to the mobo and tried starting the computer by briefly touching the pins on the mobo With a metallic object but it gave the same problem as before. So the fault is not with the power button either.
What could be the problem? Can a bad capacitor cause this problem? I think I have noticed a minute quantity of some sort of brown powder over one of the capacitors of the motherboard. I am not sure if the capacitor is damaged though.
When I try to start my computer by pressing the power button, the first time it starts and stays on for one second only and then switches off, it does not even reach the POST screen. it switches off within a second after it starts. And when I press the power button again in this state it does not start at all. not even for one second like it did the first time. Then I have to switch off the main power supply to the computer and switch it on again before the power button works but again the computer starts for may be one second then switches off. If the main power supply is kept on and the power button is pressed again then it does not work. then again I have to switch off the power supply and switch it on again to make the power button of the computer work again. This way I have to switch off the power supply and switch it on and then press the power button of the computer and after several such attempts while the computer stays on for one second and then stops, it finally boots up completely. I have noticed that when it finally boots it makes several clicking noises before it starts.
When you are asking for help, always start off with the system specifications.
This could Omega Seamaster 300 Nato Strap very well be caused by a bad PSU.

If not, continue.
Before you go out and replace the motherboard, you should do some serious troubleshooting first.
TBH youve basically answered your own question; your mobo is obviously your issue.
and that is where the fun really begins.
Make sure you plug the CPU power cable in. The system will not boot without it.
Narrowing down the cause of the issue is going to be rather tedious, the clicking noise is coming from an overcharging capacitor.
I have tested the following beep patterns on Gigabyte, eVGA, and ECS motherboards. Other BIOS' may be different, but they all use a single short beep for a successful POST.
The following is an expansion of my troubleshooting tips in the breadboarding link in the "Cannot boot" thread.
If you have power and no beeps, suspect components in likely order are PSU, motherboard, and CPU. CPU failures are pretty rare.
Bad caps, although they still happen, are not the problem they were 5 years ago.
Work systematically through our standard checklist and troubleshooting thread:I mean work through, not just read over it. We spent a lot of time on this. It should find most of the problems.
Check for line power at the PSU input. Extension cords, power strips, and power cords do fail.
You can turn on the PC by momentarily shorting the two pins that the case power switch goes to. You should hear a series of long, single beeps indicating memory problems. Silence indicates a problem with (in most Omega Speedmaster Moon Replica
likely order) the PSU, motherboard, or CPU. Remember, at this time, you do not have a graphics card installed so the load on your PSU will be reduced.
In summary its about time to get your wallet out and get yourself a Christmas prezzy.
Also, is there any software application to diagnose this problem?
I always breadboard a new build. It takes only a few minutes, and you know you are putting good parts in the case once you are finished.
In my opinion, dont even bother trying to fix it and just go ahead and grab a new mobo. It is likely the the capacitor with brown powder which is the issue but the real question is what cause that capacitor to overload Omega Watch Winder Box Price
