I put together a computer today and I find it funny that it doesn't turn on my monitor, no beeps  I cant see anything, the only THING that is working is the fans, hard drive ,dvd rom and the fan for the pentium other wise the video card s fan does not run so I know that is not responding .I tried connecting to the video card and also on the mb, I removed the video card and no video from the mb Is this a dead mb or am I missing SOMETHING?
barracuda seagate 1tb
nvidia 1024 mb ddr3
biostar t 41 HD express chipset
intel pent e 6700 775
4 gigs of memoryDo a few cold boots with the vid card removed and then retry the onboard...
You may have a dead vid card.Yep did that  I still dont get any video from mb  should I return?I would...and test the vid card on another PC to make sure that may NEED to be returned as well...Hi

Looking at the picture and manual for the motherboard there needs 3 connections from the power supply to the motherboard. Do you have a 4 pin molex connector plugged into by the pc1e slot as well as the square connector and the main power connector.

I hope this helps

  Ya you MIGHT not have all of the power connectors to the motherboard. If not the motherboard may be fried. Good to test all the components on a known working PC too. Might be having a shortage of power from the power supply.
