Newly built pc doesnt work

[TroyTRFC]

Ive just finished building my pc i push the power button and the psu fan and cpu fan both spin once then stop, whats wrong? I made sure that i was very careful with the mobo.

Got the standoffs under the board and in the right places? Got the 4/8 pin CPU power connector plugged in?

 

[TroyTRFC]

Yeah all done and checked and rechecked

If your runnning a video card/s have you got the power connector/s in? Could try resetting the bios with it unplugged and push the power buttom a few times to discharge the power supply, plug it back up and see what happens. What setup have you got? Power Supply too.

I just removed the graphics and powered it up and it is working so what does this mean an what can i do to fix it

Did you have the 6 pin pci express power connection going to the video card?

 

[TroyTRFC]

Ye that was plugged in

 

[johnb35]

Then assume its either a bad video card or bad pci express slot. Check the bios to see if there is a default video setting to use dedicated card first and then onboard.

When you say it was working with the video card removed. Does that mean you were using the onboard and it booted?

 

[TroyTRFC]

Ye

Dont guess you have another card you could try in it? Try resetting the card and the PCIe power connector (use another one) again and see what happens. Could have been a loose connection.
