First PC Build And It Won't Boot Up :( Youtube Video Inside!

Video and links to the components at the youtube link here

I've used the videocard in my brothers PC and it worked. I thought it was the motherboard so I sent it back and had a new one shipped in and nothing changed. With both motherboards the PC would shut down several seconds after turning power on, but any future time I turn the power on it just runs as seen in the video. I also used my brothers PSU and had the same result. I'm starting to think bad cpu but don't really know what to do next. Any help is very much appreciated I'm getting desperate depressed and stressed!

Edit - Also, the HDD light does not light up. Don't know if it's supposed to or not at this point.

Looks like your CPU fan is connected to the system fan header instead of the cpu fan header up the top of the mobo. try changing it and plug it into the port on the motherboard called CPU_FAN. If the fan does not spin after a few seconds switch it off, let me know how that goes

First,
http://www.tomshardware.co.uk/forum/274745-13-step-step...
to make sure that you didn't overlook something obvious.

Second, 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.

Third:
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: 5 volts always on. 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.

It's a fairly mainstream brand though so it should be support I would imagine. They even state they can't list every single ram that is supported.

My CPU fan is in the right location, the label on the mobo is just in a bad location. Other people have been saying that that a 3570k won't boot up z68 chipsets and that they need a previous gen. CPU to load up the bios so I can get the bios update to make the z68 compatible with the i5 3570k. Also, I'd have to go out and purchase a speaker because my case didn't come with one. I ordered a z77 chipset board and will update this thread again in a few days when it arrives. If that doesn't work I will purchase a speaker and try the breadboarding.

The problem was the z68 mobo. Without the updated bios it wont boot an ivy bridge. Put a z77 chipset mobo in and it runs perfect.
