No Display On New Build

[jshpik1]

I put together a computer from scratch and I have a tad problem. There is no display on the monitor on first power up. Now it's obvious all the 2 hard drives are spinning, the green led light is lit up on the mobo, everything has power, there's just no display on the monitor.... I'm flaming mad because I've spent to much time trying and yes reading, trying to figure out what's wrong. The graphics card is and eVGA nVidia 7800GTX (connects via PCI Express x 16), the fan is spinning on it although there aren't any led lights associated with the card. I'm starting to think there's a problem with the mobo but that would be a huge pain in the arse to fix, I'd have to disconnect everything, mail the damn thing in, then wait for New Egg to mail me a new one, so please tell me it's something else! Any help or input is appreciated, thanks!

Welcome to PC Mech forums

Can we have your sys specs including the brand/output of your power supply unit and the monitor? Is the monitor a known-working monitor or is that also new?

There are several things thatare causes for no video on a new computer build:
Not all of the power connections are made to the mobo and video card.
Under sized PSU.
Using an ATX PSU where an ATX 2 is required(using a 20 pin PSU on a 24 pin mobo).
Video card not seated completely
Ram not seated correctly.
HSU not fully latched or on correctly.
Bad PSU
Bad Video card
Bad mobo.
Generally if you bought quality parts,DOA parts are at the bottom of the list.

You'll have to try an out-of-case build, but if you are unwilling, then check all of the power connections.

Make sure your video card has a connection from the PSU, if it needs one
There are two power connectors for the motherboard, one 20/24 pin ATX connector, and a second 4-pin (2x2 Block) Alternate 12V power. Make sure they are both plugged in.

I can tell you I had the same problem, nothing showing on the monitor and everything else spinning and working.

Yes, do an out of box setup. My problem was a faulty ASUS motherboard sold by NEWEGG. They would not accept my return of my mb, which is such a dumb customer service strategy of newegg, so I needed to send it to ASUS. They fixed it and it is currently being delivered back to me via FEDEX.

OK, I've followed everyone's advice on checking power connections, and making sure the RAM and video card are seated correctly and securely. There are 3 different power connections on this particular mobo. 1 is the large 24 pin connection, 1 is the 4 pin 12V connection, 1 is the a 4 pin (says EZ Plug or something, it's supposed to regulate the power if I'm using dual graphics cards according to ASUS, I plugged it in just in case). I was under the impression that if there isn't enough power the system will boot up momentarily then shut back down. The power supply doesn't provide a 6 pin connection for the PCI Express graphics card so I'm using a 2 x 4 pin connection to 6 pin adaptor. The monitor is a known working monitor as well.

I didn't see the reply about the faulty mobo, as it was submitted while I was typing up the reply, perhaps I'll have to contact ASUS.... Let's assume there's a problem with the mobo momentarily, how would I go about verifying this?

Do you have the motherboard out of the case yet? If it's still in the case the motherboard could be shorting/grounding out to the case and causing what you're seeing.

I would try that Aspire PSU in another computer just to see if it really works.

I currently have the same problem at boot; the monitor LED stays orange and does not display anything. I just tried the out-of-case tuturial and everything booted up but I still got no display. I currently do not have any other mobos or videocards to test which one is faulty. Any other suggestions?
