Hi there guys. I've recently bought my new computer, and I built it today (correctly hopefully), and when I turn it on, my monitor can't find any signal from my GPU's.

My specs:

GPU: Asus GeForce GTX 285 x2 (SLi) MB: Asus P6T Deluxe V2, X58, Socket-1366 CPU: Quad-Core i7 920 PSU: Silver-Power PSU, 850W MEMORY: Kingston DDR3 HyperX T1 2000MHz 6GB (2gbx3) HDD: Western Digital VelociRaptor 150GB, SATA

And I have the HAF 932 case.

Anything else you need to know? Please ask! Also, when I boot my comp, it seems like everything is working. My GPU's are green, which means they're working. I've also tried to remove the SLi, and disconnected one of my GTX's, but still no signal from my monitor.

Any help is always appreciated. Cheers!

Are you sure the monitor is properly connected to the GPUS? Also you may want to try reinstalling the drivers for your cards. Another thing you can do is this, when it boots up and starts loading hit F8 and a menu will come up, when it does use the option "VGA MODE." If it loads up fine that way, there may be a problem with your cards.

You don't understand, this is a completely new computer, I got the parts yesterday, and I built it today. When I tried to boot it for the very first time, nothing appeared on my monitor, there is no response. I've tried to push DEL and F8 at the beginning, but nothing happens, unfortunately.

I may have built it wrong, as it's the very first time I ever built a computer, although I think I did it right. Everything seems to be running fine. The fans, the CPU, the GPU's, the PSU etc. Thanks for your suggestions though. :)

Does the motherboard have onboard video? If so, see if that works. You may have to change some bios settings to allow PCIe GPU's to run.

Also, did you plug all of the appropriate power connectors into the motherboard AND GPU's? With cards of that size, each one should have a 6 pin and 8 pin power connector.

If the cards have appropriate power, swapping each one out individually, and changing PCIe slots, just to be sure you don't have a dead card or PCIe slot.

Doesn't matter, sometimes you may just get bad parts, but like soleutator said check and see if your motherboard has an integrated GPU, one easy way to tell: look on the back of the case for an HDMI or DVI port, and it should have a small image of a monitor on it.

Nah, it hasn't got an intergrated video card, however my GPU's have DVI ports? My monitor requires VGA cables, and therefore I must use this "SCART" thing. I have little knowledge at this area to be honest. A friend helped me, he was clueless on what it could be also.

I didn't understand much of what you just told me Soleutator. I just used the PCI-e cables onto it? (Or my friend did) They are 6 pins. Lol, I'm probably just confusing myself here.

I had this problem and it was a dead CPU.

Does the PC make any post beeps?

If so, then one of the GTXs may be bad(despite the said indicators). I wouldn't rule out the DDR3 sticks either.

It might even be something as simple as a broken VGA cable.

Thanks a bunch for all the replies, but I think I've found out what's wrong, and it was either a dead motherboard or my CPU. Most likely the motherboard. I'm going to call the manufacturer today and ask if I can get two new ones. And no, it didn't make any beeps. However, if I took my RAM out, it did. So nothing was wrong with my GPU's :) I even tried with another GPU, but didn't work, so I'm quite confident that my MB is dead.

Cheers guys.

No video signal means no video signal. Either the cards aren't sending one or the monitor isn't receiving one.

The first five steps are, in this order: 1) Make sure you're using the correct DVI port. It should be the lower (left) port on the upper card. 2) Check the cable. Test it on another machine if possible. Replace if not. You're also not using a SCART out of the video card. You're using a DVI-to-D-sub adapter. 3) Check the monitor if not already known good. 4) Remove both cards and test individually in a known good system. 5) If both cards check out, power up your system without either installed. You should get a POST code. If not, you motherboard is most likely bad.

Bad, but not utterly failed memory should still allow for successful POSTing. Totally dead or missing memory or CPU will result in POST failure with beep code, as will dead or missing video in most situations.
