Computer boots up, but monitor and speakers won't

I just finished building a new pc and hooking everything up (Parts list at the end of post.) The computer boots up, but my monitor immediately says "Entering power save mode" when I turn it on and the separate speakers also don't seem to be working as I didn't hear any POST beeps nor is the power light turning on.

Two specific questions, besides these I need any ideas you guys have for what might be wrong.

1. I only have the VGA cable plugged in for the monitor. There's also a DVI-D connector but I don't recall getting a cable for that. Do I need it?

2. When connecting the speaker to the I/O panel, I used the green-colored port because the wire from the speaker was the same color. However, that colored connector is labeled as some kind of input while a pink connector next to it has the headphone symbol. Should I switch the speaker cable to that pink one, or does it need to be matched with its color?

I had Geek Squad set up the internal cables and make sure that I installed the components properly so I can only assume that everything inside the computer is set up right.



Parts:
Asus Z97-A motherboard
Sapphire Vapor-X R9 290 gpu
Corsair Carbide 500R case
G.Skill Ripjaws RAM
Intel Core i7-4790K processor
EVGA Supernova P2 psu, 1000W
TP-Link n900 wireless adapter
Dell S2240M/S2340M monitor
Logitech Z323 speakers

It goes into power save mode because you have it plugged into your onboard video instead of your GPU. VGA/DVI makes no difference, except in this case your GPU does not have a VGA connector, so you're going to need a DVI cable or an adapter.

If you don't have one at the moment (an adapter possibly came with your GPU) then you can take out your GPU and you should have video, so you can use the computer until you can get one.

Your using VGA! (facepalm) Really, just try using DVI, sine the 290 does not do VGA analog output proberly (like most modern gpus). If possible, get a dvi cable.
If you havent got a system speaker (lugs into the 4 pin header on the mobo), you wont be able to hear post beeps, even from speakers on the audio jack.
Match the colors with speakers, its always a good idea.
Attach a system speaker, then you can diagnose much more easily.

Plug your monitor into the video card, not the motherboard-I know it's plugged into your motherboard because the onboard video has VGA and the R9 290 GPU doesn't. Your speakers will not work until the audio driver is installed in Windows. Post beeps are not heard through external speakers, but rather through an internal speaker that you probably didn't connect to your motherboard via the front panel header pins.

About the HDMI, that's the thing, there is no port for that on the monitor. The only connectors on the monitor are the VGA and the DVI-D. I find that really weird but yeah.

I wasn't given a system speaker with any of my components so I guess I'll have to buy a separate one?

And about using VGA. The monitor only came with a VGA cable so I assumed I was supposed to use it. That's really irritating that they didn't provide both cables.

So the VGA cable is the reason why the monitor immediately goes to power save mode?

1. DVI is preferred, it should work with the VGA cable aswell although you might get better quality with the DVI cable.

2. Normally green port is for front speakers/headphones and pink for microphone.

As for the other problems. For not getting picture have you gone the the settings menu of the Dell monitor to check if it is taking the signal from the VGA port? It might default to the DVI port and if it doesn't do auto detect for incoming signal it doesn't know you have plugged VGA cable instead. Press any of the buttons on right side of screen to bring up the menu and find input source. Also check that the cables are properly fitted. I assume you have connected the VGA cable directly to your graphics card? The connections on motherboard are disabled when running discrete graphics card (you propably need a DVI to VGA adapter to plug the cable directly to your graphics card, should have one come with the card normally).

As for the POST beeps, they are sounded by the internal speaker if there is one and not from the soundcard connected speakers.

possibly, as tehe mobo will try to use the external gpu (with no vga) by default, and wont output on the igp, so no picture would be received when using the vga on the motherboard monitor connectors

Disregard that last post. I just set it to VGA, but it's still going to power save after.

Edit: gimme a second to catch up on the last couple posts and then I can give a proper response. Thanks for the help so far

Yes, it's fine to hold the power button until it goes off, but you don't need to just to connect the monitor to the video card. To remove the video card, yes, but to plug in the monitor it isn't necessary.

Ok, thank you. I'm gonna look around for a dvi adaptor, maybe I just overlooked it but I dont remember getting one... Will be afk for a moment, I'll let you guys know what I end up doing.

I'm gonna have to buy the right cable. The monitor specifies that its end needs to be DVI-D, but the gpu's port is just DVI, according to the box. Is there actually a difference in hardware there?

And just to confirm, I can use the computer without the gpu in it while I wait for the cable to arrive, I just won't be able to do things that are graphically very demanding like playing games. But I'll be able to at least set things up. Right?

I'm just confused as to why the card was even an issue because I had the vga cable plugged into the mobo, and the monitor was set to auto detect (and then I set it to VGA). Does the video card just being connected to the motherboard really cause signal issues even if the monitor isn't actually connected to it?

The monitor might have been set to auto detect, but your BIOS is too. You should be able to go into BIOS and set it to the onboard video, but the easiest thing to do if you aren't familiar with BIOS is to just remove the card.

Actually, let me rephrase-the autodetect on your monitor just selects between what inputs you have connected to it, DVI and VGA. The problem you are having is that you have the input on the monitor connected to video that isn't being used because it is being replaced by your GPU. There is no video being output by the onboard video, it's disabled by the GPU.

Ok, I get it now. I'm just going to wait until I have a dvi cable so as to not deal with removing and then reinstalling the card. I'll be sure to get a motherboard speaker as well. There seem to be a lot of choices, are internal speakers universal or does each mobo need a specific one?

I've yet to see an included speaker. I'll check again but most likely I'm gonna have to buy one separately. It seems that a lot of the components I bought don't come with things they really should be required to come with.

My questions are all answered for now. Thanks everybody! I'll be connecting via dvi-d after work and hopefully that'll fix it.
