When I power on my pc, I hear the fans spinning but no post and display in the monitor. I opened the case and SEE the fans of the psu, cpu, case fans spinning but the fan of the video card is not spinning. The video card gets its power from the motherboard directly and is not connected to the psu. Also I think the hard drives are not spinning, I could be wrong here. I'm afraid that it may be a faulty psu or mobo. I hope its just one or the other. Any input would be greatly appreciated. Thanks.Good evening jquin3 and welcome to CH

OK from you are writing you may have a bad video card. If the PC has on-board video remove the video card and plug the monitor into the on-board VGA port and see if the PC will boot.

If the PC still wont boot it try a different PS (power supply)

Please let us know how you make out, Mike Ok, removed the video card and used the on board video. Still no improvement. The hard drives are spinning though and the optical drives are working. Also I FORGOT to mention, once I turn it on, I cant turn it off or restart it with the power button of the pc. I have to remove the plug from the socket to power it down. I still havent tried to use a different psu because I dont have a spare. Good evening jquin3 and welcome BACK

What model PC is your computer (i.e Dell C521 or HP a6400f ETC)

Another thing you can try

When the video card was removed and you tried to boot it did you get anything on the display?

#1... Remove the memory the PC should give you a set of beeps. If the PC does give you beeps put the memory back in 1 stick at a time until you have the failure. There maybe a bad stick of memory. How many do you have.
#2... If the memory is removed and there is no beeps it is possible that the system board / motherboard is bad.

Hope to hear back from you soon, Mike Yeah, there's no display in the monitor whatsoever. Its a built pc so no brand. Tried removing the memories (2gb x 2) but even that didnt elicit an error beep. I'm beginning to suspect that it might be a bad motherboard. I just hope its just the motherboard if that's the case.Good morning jquin3 and welcome back

It is very possible most aftermarket motherboards have a built in speaker so yes you should have heard a beep with the memory removed (these speakers are a round black barrel with a small hole in the top of it) . The PS still may be bad if the "Also I think the hard drives are not spinning" are not spinning. Do you know of someone that has one you can borrow. The reason I am saying this is if the PS is bad you can replace it and be up and running with out re-install the OS. All PS have 3.3, 5,12 and volt wires and one of them may be out of tolerance so lets say the 12 volt side is only pushing 10 volts. Is there a local PC shop if so ask them to test the PS for you. Or if you want you can but a ATX power supply tester like this.

If the motherboard is bad you will have to do a fresh install of the OS if the motherboard is replaced, unless you buy the exact model that you have now. Because the more than likely the chipset will be different, the nic will be different and the same for the sound. More than likely windows will BSOD as soon as it is started because of different hardware.

Not to mention the PS can be bought for around 30-40 dollars on average.

Please let us know how you make out, Mike Yes, I may buy a psu tester to test the power supply. Thank you guys for all the help. I'll post the results whatever happens.
