Honestly,your best chance is to contact the seller/ebay and see if they can get you a refund. It's hard to really say what the issue is without having a test system to plug it into and taking it apart.

Looks like the card is bad bud. DOA. Contact the ebay seller and see if you can get a refund.

WAIT
i recommended the wrong product - that last one was on PCI and not PCIe
 
heres an updated recommendation https://pcpartpicker.com/product/zRckcf/asus-sound-card-xonardgx

DFX / FXSound is a software solution you may find acceptable, if not cheap.

I use it on my Laptop and Desktop to get some extra boost to my outputs.  It can effectively increase your output volume, and has nice built in equalization as well.  If you push it too far, it can become distorted, so it takes some playing around, but it is well worth it, IMO.
 
 

Get an AVR! Then connect from PC to AVR through graphics card's HDMI.
Muuuuch better, even on stereo.

hmm alright
 
 

are you connecting to the back of the motherboard or using a case's front panel?
 
Option 1: update audio chipset drivers if you havent already

Option 2: you could just buy a simple 2.0 channel PCIe soundcard 
 

The IRQ BSOD can happen any time, it could be a bad driver, a slight instability from an overclock, even a virus/crack/malware.
 
It means a program tried to access a prohibited memory address, which of course can be made by accident, on purpose or randomly by a real time pointer corruption. (a.k.a: bad overclock or bad memory).

You might get now why i'm gonna say: NOT ENOUGH INFORMATION TO INFER CAUSE. 
 

Very practical, thank you!

The i5 8600k is the right pair for the 1080, the i7 8700 and i7 8700k are so powerful only the 1080 Ti makes sense as now you'll be running into GPU bottlenecks instead with lower tiers.
 
Also a GTX 1070 Ti after overclock is almost identical to the 1080, you can save some money on both fronts:
 
Also do not get yourself mistaken the hardware is amazingly powerful regardless, you'll be capable of playing whatever game you want at high quality and high refresh rate, all it takes is adjusting the settings which is easy to do and very rewarding:
 
It is easy just telling people to burn money on i7's but do you actually need a high end workstation level processor just to play games?

Realistic speaking this here gives you exact same gaming performance but cheaper enough to invest in nicer keyboard and mice which do have their role, believe me getting a decent mice was one of my most meaningful upgrades in life.

Better case with Tempered Glass, And a extra 1TB storage for $5 more.
Otherwise everything is a really good match for that system.

Yes the 8700K is the best option.

Most mod to higher end Z370 boards have good VRMs. Asus, Gigabyte, and MSI seem to be the go to brands for Intel systems

For the record, the correct line to read is CPU VDD (Node 0) for CPU Core Voltage. And don't mistake VID for VCore. Not the same thing.
 
Cinebench can be used as as quick test, but it's useless as a true stability test. It doesn't run long enough and doesn't allow heat to properly build and spread.
 
While Prime95 works to test stability, I often find it pushes things a bit too hard and unrealistic. I recommend Aida64's System Stability Test stressing CPU/FPU/Cache (first three checkboxes) for at least 1 hour until you find the overclock you decide to stay with. Then do the same stress test for 4-6 hours. I leave mine running overnight (6+hours) to ensure stability. I like Aida64's ability to monitor "CPU Diode" temperature and "CPU VDD" all in the same window. Just add them via Preferences. Note, if you see sensors options for both CPU and CPU Diode, choose the later. Diode should correspond to Package Temperature or Tdie in other monitoring software.
 
As long as your Diode (Tdie) temperature stays below 80c, you're fine.
 
Edit: Aww crap, somehow I missed my 1000th post. *sadface*

thats a decent result if its stable and should not pose  any problem for the VRM
Mobo sensors are not always accurate
I need to talk with buildzoid about it but generally i'm planning to measure it from the bacc of the socket to get an accurate baseline of the real vcore

bad-reporting sensor

use HWInfo64 and use the CPU sensors, not the motherboard ones

ok
there's little to no difference between a 1060 and 1070 in premiere
https://www.pugetsystems.com/labs/articles/Adobe-Premiere-Pro-CC-2015-3-Pascal-GPU-Performance-840/#Exportingto1080p-SingleGPU
and having used illustrator, photoshop, and lightroom on a hyperthreaded dual core i5 in my laptop with acceptable performance, it mainly comes down to CPU performance.
 

Get the gtx 1070. Most notably the evga one. It helps in video editing and graphic design, which is what I do also.

Personally I have a 1060 6gb, and im not a heavy gamer. When i do play AAA titles it holds up but the 1070 regardless is a good card. If your in graphic design take the extra money into account for a color accurate monitor

Biostar makes an x370 itx, but personally, id wait and invest in the ROG x370 board. My guess on price would be around 200

There is a price range selector on the left.

Amazon search for $25-$50 price range.

Honestly hope that helps.
