First Build - Nothing shows up on monitor

Hello everyone. I completed my first build today, but I am having trouble getting anything to show up on the monitor. When the power button is pressed, all of the fans and lights in the case turn on without any problem. Unfortunately, my case didn't come with a system speaker so I'm stumped. Should my first move be to get a system speaker?

Here are the parts that I used:
Motherboard - http://www.newegg.com/Product/Product.aspx?Item=N82E168...
CPU - http://www.newegg.com/Product/Product.aspx?Item=N82E168...
GPU - http://www.newegg.com/Product/Product.aspx?Item=N82E168...
PSU - http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Hard Drive - http://www.newegg.com/Product/Product.aspx?Item=N82E168...
RAM - http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Case - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Thanks in advance

System speakers are cheap and potentially very valuable.

I would pay the $5 or whatever to get a cheap one.

As far as the problem goes, is there anything that you see or hear at all? You are our eyes and ears here and everything you tell us can be valuable.

Are there any error messages?

What is the behavior of the computer exactly?

Are you sure that you have everything plugged in correctly? The 4 or 8 pin port near the processor is extremely important. Also, pretty much every part will have a power cord that plugs into it. Things that don't plug into the motherboard also tend to have cables that plug the device into the motherboard too.

Ok. I'll make sure to get a system speaker tomorrow. Would a place like radio shack have one?

All that I see when I hit the power switch is the leds turning on and the fans beginning to start (on the power supply, processor, video card, and the ones that came with the case). All I can hear is the noise of the fans.

There aren't any error messages - the monitor is simply blank. I'm fairly sure that the monitor isn't a problem; it still gives an error when it isn't plugged into the computer, but once it is plugged in the message disappears.

From what I've seen, the computer looks like it is behaving normally except that it is giving no output to the monitor.

The only things which are not plugged in are some extra sata power connectors which I did not need. I unplugged and plugged the cable going to the 8-pin port near my processor

My only other thought is that it could have something to do with my video card, due to the motherboard's lack of integrated graphics. I'll try taking it out and making sure everything gets plugged in right this time.

Thanks a bunch for the help

Work systematically through our standard checklist and troubleshooting thread:
http://www.tomshardware.com/forum/261145-31-read-postin...
I mean work through, not just read over it. We spent a lot of time on this. It should find most of the problems.

If no luck, continue.

The following is an expansion of my troubleshooting tips in the breadboarding link in the "Cannot boot" thread.

I have tested the following beep patterns on Gigabyte, eVGA, and ECS motherboards. Other BIOS' may be different, but they all use a single short beep for a successful POST.

Breadboard - that will help isolate any kind of case problem you might have.
http://www.tomshardware.com/forum/262730-31-breadboardi...

Breadboard with just motherboard, CPU & HSF, case speaker, and PSU.

Make sure you plug the CPU power cable in. The system will not boot without it.

I always breadboard a new build. It takes only a few minutes, and you know you are putting good parts in the case once you are finished.

You can turn on the PC by momentarily shorting the two pins that the case power switch goes to. You should hear a series of long, single beeps indicating memory problems. Silence indicates a problem with (in most likely order) the PSU, motherboard, or CPU. Remember, at this time, you do not have a graphics card installed so the load on your PSU will be reduced.

If no beeps:
Running fans and drives and motherboard LED's do not necessarily indicate a good PSU. In the absence of a single short beep, they also do not indicate that the system is booting.

At this point, you can sort of check the PSU. Try to borrow a known good PSU of around 550 - 600 watts. That will power just about any system with a single GPU. If you cannot do that, use a DMM to measure the voltages. Measure between the colored wires and either chassis ground or the black wires. Yellow wires should be 12 volts. Red wires: +5 volts, orange wires: +3.3 volts, blue wire : -12 volts, violet wire (standby power supply): 5 volts always on. The green wire should also have 5 volts on it. It should go to 0 volts when you press the case power button (this is also a good way to test the power switch and the associated wiring), then back to 5 volts when you release the case power switch. Tolerances are +/- 5% except for the -12 volts which is +/- 10%.

The gray wire is really important. It should go from 0 to +5 volts when you turn the PSU on with the case switch. CPU needs this signal to boot.

You can turn on the PSU by completely disconnecting the PSU and using a paperclip or jumper wire to short the green wire to one of the neighboring black wires.
http://www.youtube.com/watch?v=5FWXgQSokF4&feature=yout...

A way that might be easier is to use the main power plug. Working from the back of the plug where the wires come out, use a bare paperclip to short between the green wire and one of the neighboring black wires. That will do the same thing with an installed PSU. It is also an easy way to bypass a questionable case power switch.

This checks the PSU under no load conditions, so it is not completely reliable. But if it can not pass this, it is dead. Then repeat the checks with the PSU plugged into the computer to put a load on the PSU.

If the system beeps:
If it looks like the PSU is good, install a memory stick. Boot. Beep pattern should change to one long and several short beeps indicating a missing graphics card.

Silence, long single beeps, or series of short beeps indicate a problem with the memory. If you get short beeps verify that the memory is in the appropriate motherboard slots.

Insert the video card and connect any necessary PCIe power connectors. Boot. At this point, the system should POST successfully (a single short beep). Notice that you do not need keyboard, mouse, monitor, or drives to successfully POST.
At this point, if the system doesn't work, it's either the video card or an inadequate PSU. Or rarely - the motherboard's PCIe interface.

Now start connecting the rest of the devices starting with the monitor, then keyboard and mouse, then the rest of the devices, testing after each step. It's possible that you can pass the POST with a defective video card. The POST routines can only check the video interface. It cannot check the internal parts of the video card.

Radio Shack should have small PC speakers, yes. It is small, the whole thing is like 2 inches long. People there should be able to direct you to it.

JSC graciously posted his standard guide so please try those things when you get the speakers plugged in.

Let us know if you hear any beep codes or anything when you are doing it.

Ok. Unfortunately Radio Shack and the local computer store did not have a system speaker. Fortunately, I just was able to get the computer to start :)  . I'm not exactly sure where the problem was, but I was able to fix it by plugging DVI cord from the monitor into a DVI to HDMI adapter which came with the motherboard and then plugging in the HDMI cord to the motherboard.

One thing I'm slightly confused about (sorry for being a noob) is why the monitor is why the HDMI port works, because the board does not come with integrated video. Does the video get processed by the video card and then get sent through to the motherboard and out the HDMI port?

Thanks again everyone,

If you look on the processor it says:

Intel Core i5-2500K Sandy Bridge 3.3GHz (3.7GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 3000 BX80623I52500K

Note this part specifically

--> Intel HD Graphics 3000 <--

You have minimal capability built directly into the CPU.

This is why it is working, I think.

I am fairly sure that nothing is being routed from a video card to this HDMI port on the motherboard.

Ok, thanks for the explanation. The reason I thought otherwise was because windows was detecting (and installing updates for) the video card. Anyway thanks again for all the help.

If your computer detects that no display is plugged into the video card and a display device is plugged into the motherboard then it will instinctively try to use that instead.

That being said, I would feel angry if it was me for having a wasted 560 TI sitting in there. Are you sure you don't want to try to get things to work when plugged into that instead?

Forget my previous post - you were spot on. When I opened the nvidia control panel it says that no nvidia gpu is connected. I'll try to plug it in now and hopefully I'll have more luck now.

EDIT - Now plugging it into the gpu is working. Computers sure are funny things. :p
