system wont boot up!! help

[bajron69]

MY system does not recognize my keyboard nor will it go past this screen? The POST does not even start up what could be the problem

We could do with your system specs and some more info. Any beeps and such when booting? Do your fans spin up?

 

Most boot problems (at least in my experience) are down to faulty RAM. Try booting with one stick at a time.

try clearing your CMOS. and ya what iSaeko said probably a ram issue 

[Ookami]

Did you tried pluggin it into other USB ports? Also since its Asus mobo try to press "MemOK" button right after powering it.

When I had the same issue the OP was having clearing the CMOS solved it for me

Btw. That is your POST screen. It does diagnosis on background. You have to set it from BIOS to show the actual information.

There is a billion posts with the same situation read some other threads.

Here is a list of things you can do from the sticky post up the top of the trouble shooting forum.

The machine doesn't do anything. No beeps, LEDs or spinning fans.

Check if your power cable is firmly plugged in on both ends (you would be surprised how many issues this resolves)

Check if the power supply (PSU) has a button to cut the power to the machine. Check if this button is in the position denoted with ON or I

Check if EVERY power cable is plugged in securely, reseat if necessary.

Check if the power button is installed correctly (consult your motherboard manual)

Try shorting out the pins you connect the power button to manually. If this powers on your system, you have a faulty power button.

Check with a device of which you know that it works if the power outlet you're using is actually providing power.

If this hasn't solved the porblem, check if your PSU isn't dead. To do this, you can follow these steps:

Unplug your power cord and/or flip the switch on the back of the PSU in the position denoted with OFF or 0

Unplug every connector coming from your PSU (this is very important)

Using a bent paperclip, short out the green wire on the 24 pin header with any of the black wires, like so.

If you have a PSU that shuts down its fan under low load, or a PSU that is fanless, connect something small like a hard drive to it.

Plug in your power cord and/or flip the switch on the back of the PSU in the position denoted with ON or I

If the PSU does NOT power on (the fan/hard drive you connected should start spinning) after following these steps, your PSU is in all likelyhood defective. Request an RMA.

If the PSU DOES power on, then the problem is most likely your motherboard.

The machine does power up, but my screen remains black (no POST).

Make sure the cable coming from your monitor is attached securely to the graphics card. Also make sure it is securely attached to the monitor itself.

Make sure your monitor works by testing it on a different computer.

If you have both a dedicated GPU and an iGPU, try your monitor on both the outputs on the graphics cards as well as on the motherboard.

Make sure all connectors and cables are plugged in securely, reseat if necessary.

Make sure your RAM. CPU and GPU are plugged in securely, reseat if necessary.

If the motherboard you're using has debug LEDs, check the error code and consult the motherboard manual to see what it means.

If you have a debug speaker connected to the motherboard, note the beep sequence and consult the motherboard manual or this thread to see what it means.

Try clearing you CMOS.

Try booting your computer with only a motherboard, CPU and one stick of RAM attached (if you don't have an iGPU, plug in your GPU as well ).

Make sure your GPU works (if you have a dedicated one), try it in another computer.

Make sure your RAM works, try it another computer.

Make sure the RAM is compatible with your CPU and your motherboard.

If the PC still doesn't POST after this, create a new thread and, as explained here, post IN FULL DETAIL about your problem. Make sure you include the following:

System configuration

Troubleshooting steps you already did

Any additional information that may be relevant.

Lastly, if you find any mistakes/grammatical errors, inaccuracies or missing steps in this post, please do post them in a comment so I can fix it.

I would remove all your USB devices and network cards/sound cards to see if it boots.
