pc not booting but fans are spinning always

[swagat_panda]

Everything was fine until yesterday afternoon when the pc got off without even touching or removing any wire. Then i tried to reboot again by pressing power button but that didn’t work at that moment. But the pc managed to turn itself on after sometime of pressing the button . Then i completed and saved my works and shut it down but then i noticed that the fans are spinning even after shut down and the LED (only HDD LED) was on.
Then i opened the side case and cleaned my cpu’s heatsink and put it back in.Now pc isn’t booting . But mobo’s green light is glowing and also all the fans (cpu & case fans) are all the time spinning and only go off when i pull off the power cable . Main problem is yesterday it was booting bu today it is not booting and when i press the power button nothing hapens. Monitor goes on for just a second and then goes off. Fans are revolving always

Any suggestions will be appreciated

Hi swagart and welcome to PCHF

Did you ensure all the hardware is properly seated? When the PC doesn’t turn on, it likely means either a faulty hardware or improper connections of the hardware

I have been using this desktop for 3yrs and never got a problem like this

Let me get some extra help here. Please note that response times will vary as we’re all volunteers and we’re all around the world.

In the meantime, can you give me more information about your machine?

I have a Asus H16M-K motherboard
Intel core i3-3210 3.2ghz
4gb ddr3 ram
Asus nvidia geforce gt 610 2gb graphics card

Anyone here??

Hi swagat panda, welcome to PCHF!

Since your motherboard includes an integrated video chip, try booting your computer using your motherboards integrated video adapter instead of the video card. Also remove all but one stick of RAM and test the machine.

As jmarket said, try reseating all the power cables connected from your power supply to your motherboard and see if that helps.

Do you have another power supply that you can use to test the machine as well to rule out a faulty power supply?

Hope I can butt in here, before trying to see if your integrated video works remove your existing Nvidia card first.

Nope i don’t have another power supply but yesterday my computer technician tried to boot normaly and the computer actually started but it shows to choose bootable device. My technician also loaded windows 7 once but at the time of next boot the pc again shows to chhose bootable device . So it’s very unclear & confusing

Will surely give a try

Today i tried to boot with the integrated video chip of mobo and voila!!!.. it worked like charm but i had yo install window 7 ultimate again and pc is running smooth
So my nvidia card is bad or what??

[jmarket]

It sure looks that way. Even without drivers your Nvidia card should work through the generic Windows driver. I would suggest you put the Nvidia card back in and connect your monitor to it using the same cable as when it worked with the onboard video. If it doesn’t work at all then, no video, then remove it and place it in the bin.

Again that problem appeared in the afternoon today and now pc can’t boot normaly even if the display cable is connected to onboard gpu. Cpu fan and case fan are revolving always just like the previous times. I am very much confused what to do??

If you have the Nvidia card removed it would seem to rule out the video GPUs as the issue. I shall summons some more help for you, perhaps as a test you could boot from a live linux disk/flashdrive.

Do you see the motherboard splash screen with the NVidia video card removed and you using the onboard video adapter? Do you hear any beeps from the motherboard speaker if you installed one?

Did you also try resetting the BIOS/UEFI settings back to default values?
