pc not booting but fans are spinning always

[swagat_panda]

Yes after booting with the onboard gpu i hear clear beep sound and strange thing is that pc is completely booting to the desktop ànd i can use the pc for just 5-10 min afterwards monitor loses signal and goes off but all the fans and the blue LED light on the front of the case is glowing but the red LED goes off.

Sounds like the PC is overheating or there is a faulty hardware component.

If you haven’t yet, reseat all the power cables that are plugged into the motherboard and reset your BIOS/UEFI back to its default values and make sure you are not overclocking any components either.

If neither of those things help, then I would look at swapping out the power supply with a known working PSU and see if that alleviates the problem.

Yesterday my friend who is a engineer told me that the problem is in the motherboard . May be a capacitor or a diode is weak so that it is storing electricity even after shutdown which is not normal. Due to this reason the fans are revolving just after switching the main power plug into the board. So those capacitors or diodes need to be replaced. What do u guys think??

I think you should try what Evan Omo suggested previously.

BTW a capacitor by design will store an electrical charge for a period of time after power has been removed. I suggest you follow Evan’s advice for a computer experts diagnostic approach rather than rely on what may be expensive guesswork.

What do u guys think??

We don’t know what the cause of this issue is. After you try my above advice then yes I would say a faulty motherboard is a possibility, but its going to be helpful if you start with troubleshooting the most obvious things first and move to the larger and more expensive components later on.
