Can mobo fry gpu?

[Laurysss]

I was running asrock board , fx 8350 and r9 270. I plugged in via usb my keyboard that got wet accidentally. The screen turned brown with artifacts. Tl;dr : Gpu fan spins, windows boots, when trying to install drivers the screen just goes black- no input signal.  My question is : i am getting a new gpu and I am worried that the mobo could fry the new gpu aswell? I am certain that the wet keyboard in some way damaged the gpu.

The keyboard isn't going to do crap to your system.

 

I'd be more worried about the motherboard and PSU.

But the keyboard did f-up my gpu. So what should I do? Put the new gpu in? As I said the pc works just cant get gpu drivers to install.

I highly doubt the keyboard messed up your GPU.

 

In order for it to mess with the GPU, it would have to send a power surge through the motherboard, which isn't going to happen because of USB overvoltage protection. And even if the overvolt protection didn't work, it would fry your board, not your GPU. The highest suspects would be your motherboard and your PSU.

 

Test the GPU in another system, with all known good parts. Maybe a friend's or relative's system.

The gpu has the same issues even on another system

Then the GPU has the problem.

It's coincidental then that your GPU got fucked. That, or a crappy PSU that allowed a short to happen frying something as a result.
