:pfff: 

I recently purchased the following:
Cooler Master HAF912
ASRock Z68 Extreme3 Gen 3 MOBO
i5-Intel 2500k CPU (With the stock CPU Cooler)
Seagate Barracuda 500gb HDD
G.Skills Ripjaws DDR3 1600 2x2GB Ram
Corsair CX600 PSU

and my Sapphire Radeon 7850 is delayed.

Anyway, I followed the MOBO's manual to properly install my CPU and the CPU Cooler. The ram is in, not side by side. Not too sure how to install the HDD but there are 2 wires attached to that that links to the motherboard (SATA3 I think). I attached the case fan wires to the MOBO's and the front panel case fan wires to the PSU to see if either would work.

When I flick the power switch on (PSU) then click the power button on my tower, I get a red light that slowly fades away and nothing is spinning, no sounds, no nothing. Please if someone could help me... it would be greatly appreciated, thanks all. :cry:  :cry:  :cry:  :cry: 

EDIT:

I also don't know where to plug in the AC'97

My I/O panel is touching... one of the things, do I have to take the MOBO out and flatten it?

I don't know how to take the front panel of the case off, it's like a screw...? but not.

EDIT: I got some pictures... They're terribly editted but please bear with me. ><

sound link you forgot a cable or you shorted the mb out to the case. on new mb there a 24 pin atx cable for power and a 4 or 8 pin atx cable for power near the cpu did you plug both of those in. also check that your ram is seated. i would if it still wont power up take the mb and power supply and put them on top of the mb box that it was shipped with and see if it power up. if it does then you had a stand off missing or somthing like the i/o shields was shorting out the mb.

I connected the 24 pin ATX Cable, as well as the 8 AYX cable. The ram is... well the two little knobs are looking exactly like all 4, except with the RAM stuck in it.

What's a "stand off" and how can the i/o shield "short" out the MB? Not sure what shorting out means, sorry. I'm 100000% amateur.

I would double-check the 24 pin power cable again. Sometimes on new builds the stiffness of the cable causes it to torque out just a hair. Just push on it to see if it moves in a bit. You can try that on the 8pin CPU cable as well(Also make sure the 8pin power cable is the one for the CPU and not the PCIE one for the graphics card. The PCIE one will have 2 parts one 6pin and one 2 pin).

Yeah the 24 pin seems to be in there, and the 8 pin clicked in, yes it was near the CPU as I have not yet found a place to fit the PCIe ones. ><

in the mb case of parts they send you 5-10 brass or copper screws.one end is threaded the other has threads to screw the mb down. if you dont put them under the mb the mb will ground out or short (in house wires there a + and a -) side on a lamp or any device with power. power flows in one side of the wire and out the other back to ground. a short is when you cross the wires or short out a compinant to ground or the hot side. (called a dead short). in new ps and mbif they see a dead short they wont power on you may see a fan twitch. the i/o shield or filler plate that goes on the bace of the mb case that has the usb and sound cart ports they have metal fingers on them sometimes there too long and can tuch parts on the mb there not supose to tuch.

First, look at this:
http://www.tomshardware.co.uk/forum/274745-13-step-step...
to make sure you didn't overlook somehing simple.

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.
http://www.tomshardware.com/forum/261145-31-read-postin...

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. Breadboard with just motherboard, CPU & HSF, case speaker, and PSU. At this point, if you do not have a system (internal case) speaker, you really need one.


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, LED's, or fan activity:

Check for line power at the PSU input. Extension cords, power strips, and power cords do fail.

If you have power and no beeps, suspect components in likely order are PSU, motherboard, and CPU.

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 green wire should read 5 volts and drop to around 0 volts when you press the case power switch.


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.

In the step-by-step guide, it says this...:

Install Heat Sink – Review your manual for specifics for your heat sink!
Here is a more detailed guide on installing the Cooler Master Hyper 212 Plus... Installing the Cooler Master Hyper 212+


Remove the heat sink from the box/protective covering.
Prepare the heat sink bracket and screws.
***Install the motherboard mounting bracket on the back of the motherboard.***
I'm not sure what the mounting bracket is...

on the images on the sales page. the last one with the items lined up. on the far right is the thermal paste tube. next to that is the mounting bracket for the heat sink. that goes onto the back of the mb. (some of the come with a rubber spacers or lable to keep that part from shorting out the bottom of the mb. the heat sink is then held in with the bracket with the four screws that go into the mb and line up with the bracket. trick it to dry fit them once then put a small dab of thermal past on the cpu and use a credit card to spread it like cake frosting on a cup cake. you dont want it to oooze out like toothpaste and short the cpu out.

My cpu cooler was the stock one from the i5-2500k... I'm not sure if anything like that came with my motherboard either.. ><

I also don't know where to plug in the AC'97

My I/O panel is touching... one of the things, do I have to take the MOBO out and flatten it?

the front case audio header is number 34 on your mb guild. that if your mb case header plug is pinned the same way. i would do what been posted and try and bread board your and see if it posts.

only if you want a bread bowl with your soup :)  bread boarding is just putting the mb on a table with the anti staic bag or box under the mb so that the video card will not fall out of the pci slots.

Seriously, no disrespect but what the ***. Why doesn't it work.

How do I turn everything on, when set up without a case? (Please don't tell me to short some wires, just direct my fingers... No big words)

EDIT: When I turn on the PSU, I hear a very faint and short beep. It comes out of the PSU so I don't think it's anything.

Do I HAVE to have that internal speaker thing?
Do you guys not know what the problem is?

EDIT2: I found the internal system speakers but it makes no sound. The cords of my Corsair CX600 are all wrapped up

if you have the ram..video card and mb together all you need is to tuch or use a jumper on the power switch pins on the mb. just have the switch on the power supply set to off. when you turn the power supply switch to the on postion it will power on the mb till you turn the power supply switch off. if you dont want to put a jumper your power switch header cable should reach outside the case.

I have the mobo with CPU and CPU cooler installed. I also have it connected to the PSU. The power button on the Mobo doesn't seem to do anything. How do I touch the power switch pins? Just with fingers? Will it hurt? :(

small flat screwdriver...but mb wont post without ram and video card unless the cpu has one built in. one thing to check if you have an older or cheap power supply is the voltage switch...(it be red) set to your country power. the old ps with the red switch will be 110v us or 220. having the switch in the wrong setting wont let a pc power on...most new ps dont have that switch there auto sensing.
