Hi guys I have just finished my first build and have tried switching it on. The first time the Boot device LED light came on, so i switched it off and pulled out all the plugs, I checked my optical drive and Hard drive, disconnect and reconnected the cables to make sure they were fitted correctly. I also disconnected my gpu and refitted it again. When I switched the computer on the second time the LED light was gone but my monitor is showing "no input".

My parts are:

case:
Nzxt Phantom

cpu:
i5 2500K

Motherboard:
P8z68 Pro/Gen 3

GPU:
gtx 580

PSU:
Corsair HX1050


Please help!

Thank you

What RAM are you using?

What happens when you push the power button? Any movement that you can see? Do any fans turn on? Do you hear any sounds?

Is the PSU power cable plugged in? It is either a 4 or 8 pin cable and located right next to the CPU. If it is not in then it won't ever work.

Thank you for the quick reply!
All the fans seems to be working, including the psu fan, and the gpu lit up for a second as well. I put my ear right up to the hdd and i think i can hear that too. Im using corsair vengeance lp 4gb x 2. I tried my monitor with my old pc and it was working fine.

OK, so the fans turn on. That is a good start.

Does the CPU fan come on?

Do the fans stay on once they come on?

Do you have any system speakers, either built into the case or just a little stand alone speaker that hangs off in the air? If so, do you hear any beeps from it?

The CPU fan is the only one working,( because the cables for my case fans are all male and so is the mother board so i was planning to get some f to f cables tomorrow) The fan does stay on though. I havent got any speakers in at the moment so no beeps at all, I have speakers on my monitor :(  shoud i find a speaker to plug in, would that help?

The PC speakers (internal) are different than regular external speakers. The PC speaker is only used for diagnostics and costs like $5. External speakers won't serve this purpose even if you have them.

The case fan cables should plug into the PSU MOLEX connectors.

If you go to these two links, you can see pictures of my computer

or at least an older version of it.

If you look on the top.jpg picture, it shows my PSU MOLEX connector (black) plugging into the white chasis fan connector.

If you see something plugged in on my computer that isn't on yours, you might want to plug it in.

Do you have the big fat 24 pin cable connected from the PSU into the motherboard? On my computer it is on the right side of my motherboard right above the video card. The one with colorful wires.

Anyway, I have to go eat but I will be back in like 1 hr'ish.

BTW, yes my CD Drive was disconnected. It made my PC boot faster to leave it this way.

Do the fans shut off quickly after the power comes on? Or do they stay on indefinitely? Does the computer restart over and over?

Do you have the standoffs in the computer correctly? They are little gold things that screw into the case wall and keep your motherboard from touching it.

Here is some troubleshooting tidbits from the person on these boards named JSC.

When you are asking for help, always start off with the system specifications.

However, onward to some systematic troubleshooting techniques.

Work systematically through our standard checklist and troubleshooting thread:
http://www.tomshardware.com/forum/ [...] t-problems
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.
http://www.tomshardware.com/forum/ [...] t-problems

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/ [...] adboarding

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.

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.

But all my fan cables are 3 pins (male) I do have a separate molex (black) from the case and the separate molex cable (white) but they are both male. I have the 24 pin connected.
O hey! I just turn my computer on and the monitor started working, I havent touched anything yet though...
The device boot LED light is back on though, and my monitor is showing CPU fan error, woulf that be the device boot error?

Thank you, i will read through and try working through my parts

Could you post the link again please, its just taking me to the main forum page. Thank you, i really appreciate the help
