[Help] DVI No Signal new build (PICTURES)


I just put together a new build, this is what it looks like:

HDD: SAMSUNG Spinpoint F3 HD103SJ 1TB
CPU: Intel Core i7-950 Bloomfield 3.06GHz LGA 1366 130W Quad-Core Processor BX80601950
GPU: 2x EVGA 768-P3-1360-TR GeForce GTX 460 (Fermi) 768MB 192-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
CASE: Antec Nine Hundred Two
MEMORY: CORSAIR DOMINATOR 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Triple Channel Kit
CPU COOLER: XIGMATEK Intel Core i7 CPU Cooler 120mm

Second setup this year, but this is my first Intel-based. Everything seems to be plugged in just fine, power should be more than enough, ram is set in the white socket. I am unsure how to know if the motherboard actually works, but there's lights measuring CPU usage and RAM usage and stuff, so I guess it does work. However, the Phase light is red.

Problem: I get the DVI no signal (or VGA no signal, tried both cables)

I have read and pretty much tried everything I've seen in the troubleshoot tutorial on this website about no POST or No Signal errors. However, no luck. Tried CMOS reset, plugging only one GFX card, one ram stick, no USBs, no HDD, no DVD, yet I still get the damn DVI no signal error!

I have taken pictures of the machine, so if you feel like solving a mystery or pointing the (I hope) obvious mistakes I've made when plugging cables, please do! I would also like help on trying to aim what part might be defective.

Overall view of the MOBO:

  1. if you don't have a PC speaker (buzzer) attached, attach one. Listen to the beeps. Does the board have an onboard video? if yes, try that (too lazy to check the specs for the board).
  2. Thanks for your reply pinaklonkar! Tomorow I will get a PC speaker and see how it goes. No, there are no onboard graphics. I have tried both gfx cards just to make sure one wasn't defective.

    If you noticed, there are leds indicating the usage and load on the mobo (green being low-usage and red high-usage), and these are turned on. Other stuff glows on the board as well, such as a 'clear cmos' pushbutton. Does this mean the board actually works if it can read cpu usage?



    Does anyone else have any other ideas? Sucks to put 1500$ in a build that won't boot haha, I'm getting nervous...
  3. Are all components under store/website warranty? Don't worry. Some people (like me) just don't have luck with newly built system until they are down on their knees. I built a gaming computer after years (thinking that curse would be gone), and in 2 days my motherboard had to be RMA'd and I was without a motherboard for 15 days with all the games in my jewel cases laughing at me.
  4. Ah, ok. Use your stock cooler on your CPU with good heatsink compound. First let's try with stock before you install some funky aftermarket cooler. That seems to be the problem. DO NOT KEEP YOUR SYSTEM RUNNING FOR A LONG TIME YOU MAY TOAST THE PROCESSOR.

    Also make sure ALL connections are made to the motherboard from the power supply. Also make sure your graphics card got a power supply connection if it needs one. Typically motherboards have two connections going into them one is the regular ATX and the other one is 4/8 pin one.
  5. Thanks again for into pinaklonkar!

    No luck so far with the CPU cooler, I still get the red lights indicator and the No DVI Signal, I believe all the connectors are plugged; ATX and the 2x4 pin one, then the CPU cooler, the GPU and the power/reset/etc small plugs. Apart from that, for a quick boot, Do I really need anything else? Do the case fans HAVE to be plugged?

    Ty again
  6. Without the PC speaker beeps, I am unable to proceed with confidence. Prepare for motherboard RMA regardless. Or if it is under store warranty, just get a new board already.
