Sound and Visual Problems

Hello!
Past few days my computer started to make a wired glitch.
When using Google Chrome i see straight pixel lines over some pictures.

In CS:GO the sound is distorted and high frequency noises come when there is a sound.
Also when playing Fortnite, the elements that are supposed to move on characters(like clothes or capes) are moving randomly and brutal all around the screen and at some point they disappear.

I've tried to reinstall the windows 4 times,different versions, i've updated the bios, removed all the components from mobo and put them back in, i tried all slots for RAM, i've reinstalled the graphics driver but still no solve. I've tested the GPU on another computer and it worked fine. I think is the mobo somehow, i bought it last month and it worked fine until now. The only remaining reason i can think of is that the mobo is not fixed in all the screws. i didn't placed 2 or 3 screws and it might cause a short.
Component List:
Gigabyte Z170X Ultra Gaming
i7-6700k
Asus 980Ti Poseidon Platinum
8 GB Corsair 3200 mhz

Ok, that suggest that your gpu is ok - given you did a decent stress test while it was installed on that other computer.

First recommendation is to check if your RAM is working properly - you typically using Memtest for that.
tip 1 : Use Ultimate Boot CD, as Memtest is one of the tools avaiable.
tip 2 : In some occations - a faulty psu may cause Memtest to repport failure to RAM (and after replacing psu, it repports no error on RAM any more).

So - given that the GPU is fine, this is the component I beleive is most prone to fail and cause those errors:
- PSU
- RAM
- Mainboard itself (look for bad capacitors)
