Question New motherboard - No Signal

[subasini]

Hello everyone, a couple of a days ago I spilled a very tiny amount of water on my old motherboard (which no longer boots), and since then I have bought a new one, H310M-D REV 2.0.

Now everything works fine, but the only thing I can't get to work is my monitor - it keeps saying No Signal when I connect either the GPU (1070Ti) with DP or the onboard graphics (i5-8400) with HDMI.
I should also add that there's no light on my keyboard or mouse when I boot.

I have basically tried everything from re-seating ram to clearing CMOS, etc... I can't think of anything else to do.

Any help is very appreciated...

Now everything works fine

how is everything work fine if there is no keyboard, mouse and screen output?

how is everything work fine if there is no keyboard, mouse and screen output?

By everything I mean the CPU fan, mobo LEDs, chassic fans and that stuff.

Could faulty RAM cause no signal and no power to mouse and keyboard? I could test it out tomorrow with a 4gb stick.

 

[rgd1101]

was the pc on when you spill water on the old motherboard?

test with the 1070 out and use the igpu?
check for bend pin on the motherboard socket?

 

[subasini]

Yeah, the PC was on when I spilled the water on the old motherboard, but I've replaced it by now.
I tried using only the iGPU but it just gives me No Signal.

No bent pins at all.
I'm thinking it might be RAM...

 

[rgd1101]

did the system shut down after the spill? pop from the psu?

 

[subasini]

Yeah, the system shut down and I unplugged it ASAP, but it seems like the old mobo is gone.

PSU is working fine, did the paperclip test and it's also powering on the current components with no issues.

So I'm thinking it's either the CPU or RAM which is causing the no signal and no light on mouse and keyboard.

 

[rgd1101]

what the make and model of the psu?
Could have shorted the psu.
doesn't need much to power fan and led.

 

[subasini]

It's the Corsair CX650.
Thank you for replying.

Right now it's either PSU/CPU or RAM...

 

[rgd1101]

if you have 2 stick of ram. could test with each 1.

 

[subasini]

I have already tested both RAM slots with both RAM sticks.

 

[rgd1101]

have another pc to test the components ?

 

[subasini]

No other PC to test it on, sadly.
Do you think it'd be wiser to first buy new RAM or new PSU/CPU? Thanks...

 

[rgd1101]

Buy the one that you can return?

 

[subasini]

Not sure there's a store where I live that has a return policy on non-faulty components.

I guess I'll try with RAM first - I've tried starting the PC with no RAM at all and it behaves absolutely the same...

 

[subasini]

@rgd1101

The RAM is yet to arrive, but while I wait I tested the system without the CPU. Everything behaves the same, and there's practically no difference.
Could this mean that my CPU is dead? The water might've gotten into the socket when I spilled it rendering it dead... thanks!

 

[rgd1101]

it won't boot without cpu

 

[subasini]

@rgd1101 I've tried the new stick of RAM in both slots without luck, still No Signal. I will be trying a new PSU in a bit so I can report back on that too...

 

[subasini]

Also tried with new PSU, same thing - No Signal... my CPU is probably fried.

 

[subasini]

@rgd1101 I replaced my CPU with a different one and now everything's working fine. Thanks for trying to help.
