Issue with new computer (no display) - SOLVED

RialeRiale I'm a little slowRegistered User regular
I just got finished putting together my first PC and upon plugging everything back and switching it on, nada.

The processor/ram/gfx card/etc etc are all correctly inserted as far as I can tell. The mobo has power, as do the case fans, the cpu fan and the gfx card fan. The HDD and optical drive are both running and the comp is not overheating at all (if anything, it's running abnormally cool). I've tried several monitors and several DVI cables so i've ruled that out. Seeing as this is my first build, I'm not really sure what the problem could be. I would say mobo but it appears to be running fine. I guess the graphics card could be bad? but it doesn't seem to have any issues getting power for the fan. The CPU certainly isn't overheating, and all of the parts I ordered came in what seemed to be perfectly good shape.

Unfortunately I don't have ready access to a digital camera so I can't share any pics that might help, but if someone could at least point me in the direction of a possible culprit, that would help.

    Make sure the yellow/black wires are plugged in next to the CPU and reseat the RAM.

    check that both your 8 AND 24 pin power connectors are plugged into the motherboard. Also try booting with no ram and no keyboard plugged in. If you don't get any beep codes the problem is something to do with the motherboard and you can rule out the videocard.

    8pin? i've only got a 24 pin and 4pin. They're both connected, and the only power cords not currently plugged in are a few misc fan connections I'm not using and a firewire cable.

    I tried without the ram and keyboard and still nada. No beeps, no nothing. All the fans are running and everything is obviously getting some kind of power, but there's still no display. As for the video card, should I be feeling any heat from it? Because while the fan has power, there's absolutely no heat radiating from the card at all. Is this bad/good/normal? Everything inside the case is almost abnormally cool.

    Yeah, thats not a problem then, some motherboards use 4, some use 8. I would try reconnecting both the power connectors, because your problem sounds exactly like what happens when only one is plugged in. There's enough power for the fans,optical drives and hdd to spin up, but not enough power for anything to actually run. The only other thing i've seen cause a problem like that (aside from a faulty mobo/psu which we'll hope isn't the case for now) Is the motherboard shorting on the case or heatsink. Check and make sure its not touching anything metal, and if you used a 3rd party heatsink make sure its not contacting any metal on the mobo anywhere.

    Also, try leaving everything hooked up but unscrewing the mainboard from the case, lifting it out and powering it on whilst you hold it. Might be something to do with the case.

    I had a problem pretty similar to this, which was eventually solved by reseating the processor.

    However, you said you get no beeps even with no ram. Try what the others said too, otherwise it might be a problem with the motherboard.

    Through some weird miracle everything is working fine now.

    I had a friend bring over his comp so I could swap some parts and try to determine the issue. We tried the graphics card first. Lo and behold, it booted up into bios just fine. So I thought, "Well, my card must have a problem." On a whim, I swapped my card back in... And it worked fine as well. Maybe I had a loose connection the first time I tried, or maybe just getting into bios was enough for my card to become compatible? Heck if I know, but it's been running all day with no problems. I'm just glad none of the parts were bad in the end.
