Fans turn on, MB LEDs come on, HD starts up, but no video, no BIOS beeps and USBs not connecting

[Computer_AC]

So it has been a few months since I have started trying to fix my computer. It was hit with a power surge and killed my computer. Since then I have replaced my motherboard 4 times, the CPU 2 times, the RAM, Power Supply, and replaced the case and it has not fixed the problem. The Problem is that I can turn on the computer the LEDs light up, fans spin, and I can hear my HDD start up. But my monitor doesn't display anything and my mouse and keyboard's LEDs won't light up. Also I have tried to get anything for the BIOS beeps and have not been successful.

I talked with friend of mine who has a custom computer we tried my GPU and HDD in his computer and they both work. I also have taken my computer to a repair place and he told me he tested the components and they are all good, and that the only thing he was not able to do is try it with a different motherboard since he didn't have a motherboard like mine. That is when I replaced my motherboard for the 4th time after talking with him.

Is this a sign of a bad CPU or something else. I could really use some help on this.

Try connecting a case speaker to the motherboard and starting it with no RAMs. See if any beeps.

I tried hooking up my speakers before and I tried it again when I got the most recent motherboard. I still don't get any BIOS beeps.

Not the speakers, but https://images10.newegg.com/NeweggImage/ProductImage/12-201-032-02.jpg

Oh ok, I was misunderstanding what you were talking about. I tried looking with my stuff and I didn't find one. I'm not sure if I am supposed to get one with a new motherboard or not. I see that it is an image from Newegg can you actually purchase one from them?

 

[alexoiu]

Sure.

or amazon or whatever similar.

Ok thanks! I will try that and see if I can get something out of it.

 

[alexoiu]

No problem.

Case speaker usually comes with case, not motherboard.

 

[Computer_AC]

No problem.

Hey I finally got a speaker you where talking about and I tried it and I still could not get any BIOS beeps.

 

[alexoiu]

Have you started the board without RAMs and still no beeps?

Yes I pull out the RAM and I still have not gotten any beeps.

Then board, or CPU does not work.
Try RMA-ing them both. If still possible.

Well I have had the same CPU across the 4 motherboards that I have had gotten. The last motherboard I got was from MSI itself so I would guess that it is the CPU. But at this point I'm not really wanting to assume anything.

"I have replaced my motherboard 4 times, the CPU 2 times"
"I have had the same CPU across the 4 motherboards that I have had gotten"

I suggest replacing the CPU, then.

Alright I finally got a new CPU, it took forever for it to get replaced. I finally have visuals on my monitor and I am able to connect both my mouse and keyboard. But I have a new problem. The computer will only stay on for a moment and then turn itself off.

Might be the cpu is overheating.

 

[alexoiu]

Make sure that the pump is connected and running.

 

[Computer_AC]

Ok the solution was reached. I changed the CPU fan and my computer is able to stay on and I am able to work on it. Thank you for helping me out.

You're welcome.
