Solved Start but won't boot.

December 31, 2013 at 16:43:57
Specs: Windows 7, Amd phenom II / 4g ram
My computer starts but won't boot. Please please help.

I came home during a storm (don't know if related) to a computer that should of been running. Instead all the fans were running fast and the computer not booted. Reset, nothing. Unplug the power supply...nothing. Try a different outlet...nothing. I popped mobo bios battery...no boot. It powers on, all fans and lights a go, but no boot or beeps.
My next step. After I rma the mobo, powersupply, video card and CPU...still no boot. I bought a new power supply and new ram...no boot. I tried and out of tower start incase something was grounding...no boot. Bought a new bios battery in a laughable hope...nothing. So many other little things I tried including screaming, crying and baby talk...nothing.
Please someone help me so I can love you forever. Please, my frustration and confusion over this has driven me absolutely mad.

You still didn't answer if you have the power supply connected directly to the mains or do you have a power strip or UPS in between the mains and the computer?

24 pin power connector plus the 8 pin auxiliary power connector plus the six pin graphics card power? CPU fan connected to the correct header (CPU)?

Motherboard isolated from the case by using cardboard or the foam from the shipping carton for the board?

The two comments below are copied directly from your MBoard manual.


To enable successful system boot-up, always insert the memory modules into the
DIMM4/ DIMM2 first.

Dimm slot #1 is closest to the CPU. The slots are numbered in order. 1,2,3,4 across.

Line up the video card on top of the expansion slot(s) with the display ports facing
out of the computer case. For a single video card installation, using the PCI_E2 slot
is recommended.

PCI_E2 is the slot closest to the CPU.

When you temporarily short out the 2 power switch pins does anything happen?

With the power cord disconnected, temporarily disconnect all the drives and remove all cards except video--if you're using a video card and not on-board graphics--and remove any USB devices. Plug the power cord back in and start it up. If you get the normal posting or logo screen then one of the disconnected items must be at fault.

Otherwise it's usually the power supply, motherboard or both. But you've replaced both of those already so I'm not exactly sure where to point you. Are you sure the new motherboard was good and you installed it correctly?

Sometimes a bad power supply can wreck a good motherboard. Did you replace both at the same time?

If you had the memory removed when you tried that then the beeps were probably a memory error. I guess that's somewhat good news since it means the bios is working.

You say you tried it with a video card. Does that mean it doesn't have an on-board graphics port or you just don't use it? If it has on-board go ahead and remove the video card and see if anything shows when you use the on-board.

Post the brand and full model number of the power supply and all the other hardware.

RMAing parts to troubleshoot is not good practice. Beep codes and/or codes on the motherboard should be able to identify the problem.

Did you look at the beep codes for your BIOS?

Post the brand and version of your BIOS.

Read the BIOS brand on the board and then look at the links posted by johnw above.

Do not assume the original problem and the current problem are related.

Go back to to beginning. Remove the MBoard from the case and bench test it with ONLY the following items. Set the motherboard on the anti-static foam it came with. Install the CPU/HS fan, 1 stick of RAM, graphics card. Connect the 24 pin power connector, the auxiliary 8 pin CPU power and the 6 pin graphics power.

Connect monitor and keyboard. NO other cards, cables, case wiring, etc. Verify you have installed the HS correctly with the correct thermal paste procedure. CPU fan connected to the CPU fan header. Clear the CMOS using the jumper and restore to the run position.

Plug in your power supply and start the board by momentarily shorting out the two power pins on the motherboard.

If you now get the board to POST then add the remaining RAM and try again. If still good you can now install the board into the case. Verify the standoffs are the right length and are installed ONLY under mounting screw holes in the motherboard.

If you can still POST then you can make up the case to board connection. After each step try posting again. That way you may discover a defective piece of hardware.

What a great reply thank you so much. The beeps were the ram ( because it was out) then video (because I removed vc).

I reset the CMOS but no matter what I do I can't the computer to post! This is maddening.

Perhaps I misunderstood but you can't POST without RAM & graphics.

Did you verify all the items I mentioned above? CPU fan, 8pin power, 6 pin graphics power, heat sink properly fitted?

I can only get post beeps if I remove hardware, no beeps with everything installed, and no beeps with only video, ram and CPU installed. I can't get any video so no bios. I just tested the video card in another computer and it worked fine. I have checked all your listed items and all seem to be powered fine and are functional.

If you hear POST beeps with hardware removed that means the CPU is OK and the motherboard may be OK as well.

What hardware are you removing to get beep codes.

Borrow another graphics card to see if you can then POST.

Are you positive you have all connections made up correctly?

Are you sure the graphics card is fully inserted?

Did you try booting with ONLY i stick of RAM? Try all RAM sticks one by one. Be sure to insert RAM in #1 RAM slot.

I did john, I took it to a different monitor when I tried a different outlet. Still nothing.

I forgot to mention, while it does power up everything (fans, lights) it does not power up USB. My mouse and keyboard go unpowered.

I have triple checked connections all seem a go. I can only get beeps when I have video card, ram and CPU hooked up. If I remove the ram, I get ram beeps. If I remove the video card I get video beeps. I haven't tried a new video card I will attempt that tomorrow.

Do you have any unnecessary hardware connected? External drives, printers, scanners, etc.

As per #11 above. Did you try booting with ONLY the hardware listed? You need to actually disconnect everything else from the motherboard. No drives of any kind, no extra PCI cards, no readers, no case to board wiring, etc?

You do NOT need ANY drives connected in order to POST. Booting without your boot drive should run through the POST screens and stop at a message that no boot device was found.

If your hard drive is fried it can stop the POST.

"All drives that are not needed and components not needed are disconnected".

The above statement indicated you may have had the boot drive still connected.

You need to try a different graphics card.

Boot drive is your hard drive. If you tried with only the above and see no video then you need to try a different compatible graphics card OR the power supply may be partially defective.

If possible, try the graphics card in a different compatible computer.

So to recap, the RAM is the only necessary hardware that you didn't RMA?

Did you clean off the CPU and heat sink then apply new thermal paste on the CPU when installing into the new motherboard?

Are you sure the clear CMOS jumper is in the RUN position?

I didn't rma the ram because I just bought new ram.

As far as the heat sink I did clean and reapply when I rma the CPU.

And I am pretty sure the CMOS jumper is in the run position (first two pins of three)

When testing, do you have all the case to motherboard wiring disconnected? I mean ALL, including any cables to drives, USB headers, card readers,

Are you using a power strip or a UPS power supply in the line?

DDR3 RAM modules have an offset notch in the bottom of the PCB. They should only go in one way. I have seen folks install them backwards. They shouldn't fully seat if that is done. Are you sure you are installing the RAM correctly?

Have you tried both sticks, one by one and tried them in every slot?

Yes the tower is completely disconnected, and the ram can only be inserted one way on this mobo. I have tried all four sticks separately in all four slots.

What about other hardware in the AC power line?

I know the RAM can only be inserted one PROPER way. That hasn't stopped some from trying anyway.

I am running out of ideas.

Did you happen to clear the CMOS on the new board with the power unplugged?

Is the motherboard installed in the case or out? When inserting the graphics card is the locking tang on the end engaged?

The only noticeable difference in shorting the pins is that when pins 1and2 are shorted the fans run quieter than when 2and3 are connected.

Ram and video card are in correct slots

I have tried two different power strips, three different wall outlets. I am direct into the wall now.

CPU power is connected, graphics power is connect and mobo power is connected.

The mobo is isolated from the case and is sitting on the box it came in, the power supply is also isolated

Well this is interesting....I changed my graphics card to the second PCI slot, then put in all 4 sticks of my ram and it started up. I don't understand how of what of those two things did it but so far it's working. I checked both slots before and moved a stick of ram to each slot so I don't know how that could of fixed it. If anything changes I'll update here.

I can't thank this community enough, you all have kept me as sane as possible durring this.

It might have been an IRQ problem then. Moving a card to a different PCI slot changes its IRQ.
