(Noob) Do I need a new Motherboard?

So I have an MSI motherboard and a gigabyte 1070 GPU and an i5-3570k and I think I broke my motherboard or other hardware today as I am no longer able to receive any monitor output via either the 1070 or through DVI on my integrated card. i.e. I can't even get a BIOS to show on my screen. I have tried this on multiple monitors as well.

My PC powers on but gives no signal to the monitor regardless of which graphics card I use.

This happened right after cleaning my PC with canned air.

I've tried a new PSU. I tried moving the Ram sticks. I tried CMOS reset. It powers on and I can feel heat from my CPU (does this mean the CPU is still working?)

Basically I am willing to spend a bit to fix this, but I am trying to figure out of my motherboard is the problem.

I would say it's your mobo that's the problem since the onboard graphics don't work and you don't hear any beeps it's probably dead. This happened with an old alienware of mine, the mobo died and no beeps and the onboard graphics didn't work. So I got a new mobo and worked fine.
Take the Graphics card out, take all but one RAM DIMM out. Make sure all power supply connectors are tight, make sure none of the unused power supply cables are grounding to the case and start up the PC. You may want to invest in a small Motherboard speaker, the motherboard maybe trying to send you beep codes but you will need a motherboard speaker to here them.
 


I heard 3 beeps from it one time when the RAM wasn't tight in enough. Have removed the GPU, have one RAM in and still I get no signal out to monitor. There is no beeping like there was with the RAM

I have tried new PSU, so that means it is likely the CPU or Mobo right? How can I eliminate the CPU from the equation? Would I hear beeping if the CPU wasn't "Getting through"? Would it be heating up if it was broken?
 
Any help please? I need to get this computer up and running and would prefer to not have to buy every individual part to fix it.

I think I have it down to CPU or motherboard, how can I tell which is the problem?
 
So I went through the wont boot sticky very closely and have still not found a solution.

- Bought another PSU from the store and no help
- Reseated CPU / Re Applied thermal Paste
- Removed everything except the PSU, CPU, and RAM
- I tried a single Ram stick in every slot.
- I get no video out from Nvidia GPU or Integrated GPU.
- I reset CMOS.
- Now when it "powers on" (fans/lights/no post) it will shut itself off after 10 seconds or so and loop like this.

I think I have it narrowed down to motherboard and CPU.

I get 3 beeps if I don't insert RAM but no other beeps otherwise.

The fans/power and everything turns on but no video signal.

Basically, I am trying to figure out how to tell if it is the CPU or the motherboard. Are there any tell tale signs of it being the CPU?

What would cause no video out on either GPU?
 


Thanks for the response.

It is a build I had been using for the past 4-5 years. A semi-recent upgrade was the 1070 but it had been working fine for months.

It happened directly after I tried to routinely clean the PC with an air can. I got it to boot up into windows one time after the cleaning and it non-blue screen froze. I thought maybe I had left some dust somewhere so went back in to clean it again with canned air and after that I have never been able to even get the BIOS to show up on any monitor.
 


Then something is still not connected properly.
Something got dislodged during the cleaning.
 


Yea I thought that might be the case but I essentially pulled everything out of the motherboard, even re seating and repasting my CPU, so I don't know which part would not be connected properly.

I'm more wondering if I had static discharged or something and damaged a part of the mobo but I dont want to have to ebay a z77 motherboard and wait a week+ when I am not even sure the mobo is the problem.
 


Already tried that. I get no video signal even when I entirely remove the 1070 and use the integrated GPU either.
 



No worries, I appreciate the attempts to help.

I got a DZ77SL-50K LGA1155 Z77.

Was reasonably priced and had a return policy if it ends up not working. I'll report back when I finally figure it out.
