Static shock messed up my Desktop's sound

[Clockwork757]

The case I'm using is a NZXT H440, my motherboard is a Gigabyte Z370 HD3P.

 

I tried to turn on my PC earlier and before I could touch the power button I got shocked. This also powered the computer on. It booted up normally into windows. However the front audio port seems to only be outputting random static, unaffected by any actions on my PC. It's also outputting the same thing from the mic jack. I've tried the back slots but it seems like they're not outputting anything, although I've never used them before so I'm not sure if I'm just not using them correctly. The front USB ports next to the audio are functioning fine.

 

The static noises continue while my PC is turning off and while it's off, although it's just a monotone buzz. I've tried shutting it down and unplugging it from the wall for a few minutes to no avail. Luckily my monitor has sound pass through, which works for now but I can't use my mic at all. 

 

I don't think I was charged because I touched a few metal things in my apartment before my PC, and I discharged into my monitor when I went to turn it on (it's fine). I'm not sure what could've caused this. I haven't opened my PC in over two weeks. I'm also using a surge protector.

 

Is my motherboard's sound card just toast?

 

Any help would be amazing

Unplug every front usb panel header and see if that works.

That didn't change anything.

 

On a side note, when I boot it up it sounds like it's outputting something more ordered. Like a rising tone then some bleeps and bloops that don't sound random.

 

Also I came back after a few hours, I left my pc plugged in but flicked off the switch on my power supply and it shocked me again. I have no idea what could be causing this, I haven't changed parts in over a month.

The only thing you can do with power issues (lightning, static discharge, PSU, etc) is to do a power flush of the system and peripherals.  If you are still having problems after a power flush, then the static discharge has fried a component.

 

Basic power flush usually involves these steps:

• removing all power adding sources such as battery, AC outlet, etc.
• Attempting to power on an unpowered device (hold down power button 30 seconds)
• Let the device sit overnight, some stuff needs to sit for a week depending on how much power the capacitors are holding.  Most PCs, overnight is enough.
• Try plugging everything back in
