What the guck is wrong with my PC? Sound disappearing, apps crash!

[firefly_goat]

Hey there. There's something really messed up with my PC. I recently had big problems with my Steelseries H Wireless. The sound would randomly disappear and when it did that, all the programs would crash, well not Chrome, while watching YouTube videos on Chrome when the problem arrives the video would just stop and you couldn't resume it. So what I did was just pull out the USB and plug it in again and the sound would come back! But now I returned the headset and I bought a Creative SoundBlaster Z. I have no idea why, but the sound card sounds horrible. And when I'm trying to change something in the control panel, like switching from 5.1 to headphones, the sound disappears and everything that plays sound crashes. 

 

 What the guck is wrong?? I have tried reinstall Windows like three times. I've also disabled Realtek audio in BIOS.. 

 

My setup:

Gigabyte GA-Z68X-UD3H-B3 (Latest UEFI) 

MSI Ligtning GTX 780

16GB RAM

Samsung 830 SSD (boot) 

Western Digital 3TB

Intel I7 2600K 

Windows 10 64-bit

XFX 850W PSU

Creative SoundBlaster Z

Well I disabled the on-board sound card in BIOS and uninstalled the Realtek Drivers.

But why? I have a separate sound card and I disabled it and uninstalled the drivers because of the problems. I have tried reinstall the Realtek drivers lots of times before I bought the sound card!

try using the motherboards sound. sound cards are mostly useless imo.

Well the problem will still remain, just that I'm avoiding it. Because this seams to happen to every separate sound card. Like every USB-headset, and the SoundBlaster. And the sound from the onboard card is not very good at all!

I'm so F-ING stupid! I tried all this things to fix this "problem"! The problem with the H Wireless was because of faulty headset and the "problem" with the sound card was that I plugged in the 3.5mm cable in the wrong port, I plugged it in one of the surround sound ports. Haha!
