Software fried Mobo?

[Flowbucket]

Hello,

 

I have been working with RainMeter to update my desktop background. I downloaded a power on/off button and tested it. My computer shut down, then it wouldn't turn back on. At first I thought it was my PSU because the PSU fans wouldn't turn. However, I tried unplugging everything from my motherboard and it powered on, and as I slowly plugged 1 thing in at time I discovered it was the argb wire somehow (haven't connected those dots yet). 

 

I did the paperclip test on the PSU and no issues there.

 

When I leave that unplugged, the fan lights turn on, the PSU/GPU/CPU fans all power on to 100%, but BIOS doesn't post and there's no beeping or blinking of any lights that indicate it is trying to post.

 

When I try to power on without ram plugged in nothing changes, I tried each 4 of my sticks in each 4 of the slots and nothing changed.

 

I tried resetting CMOS, again nothing.

 

Did this shortcut really fry my motherboard? Is there any chance it's my processor?

 

Mobo: Asus z390a

Ram: Thermaltake 4x8 3600 Mhz

CPU: i5-9600k

PSU: CX 750M

I don't think software can fry your computer (atleast not like that), but what happened here I don't know. You could try reinstalling windows from a USB stick/ DVD drive maybe?

I can't even get to the BIOS screen to do that though that's the issue, it is just stuck with the fans blowing at 100% and the default color scheme. USB components are getting power through the motherboard.

 

I've never ran into something like this before I'm completely baffled.

Yeah that's really weird. I thought you could maybe bypass the POST screen by having a Windows USB stick in, but yeah, as you said it probably wouldn't work. Hopefully someone else here can help you!

Do you have a graphics card? because that sounds like a graphics issue new motherboards don't just die like that.

It's a 2070 and haven't had an issue with it otherwise. These aren't new components I've had them for about a year and never experienced something like this.

to me this seems like an fault with the Northbridge but these faults tend to happen with older motherboards (2011) i am not sure how software can do this!

^ Correlation is not causation.Your RGB circuit is probably gonezo. I have an ROG Z370-E that blew up an RGB header as well.

 

Software can kill a motherboard, but not like this.
