Windows 10: Losing Gigabytes everytime when i start up

Hello. I am using a Asus X515JA computer that is 3 months old. In just 2 DAYS i lost 8 GB from my Intel NVMe, does anyone know why? And i tried every single way to free up space from my computer. I didn't use MRT.exe because i have some apps that looks malicious in my D: drive, but the -8GB is at the C: drive. I have almost 4GB worth of apps but my total was 130GB then it went down to 127 and 122. How could this happen?

gigabyte Z370 HD3 + Samsung EVO 970 won't install Windows 10

Newly assembled system:

• Gigabyte Z370 HD3 V1.0 motherboard
  
• Intel i7-8700 CPU
  
• 2x DDR4-3200 16GB RAM (F4-3200C16D-32GVK)
  
• Samsung EVO 970 500 GB M.2 SSD (MZ-V6E500)
  
• Thermaltake TR2 S 500 W PSU (TRS-0500P-2)
  
• Deepcool Tesseract case (seems doesn't matter)
  

All components come new, unpacked.

Windows 10 Pro installation failed at the step "Getting files ready for installation." when about 70-80% complete.

I used both the original Windows 10 Pro DVD and a USB stick prepared by a Microsoft tool; the result is the same.

I tried to use the pre-installation SATA driver from the Gigabyte website.
Once I installed this driver at the step "Where do you want to install Windows", my M2 drive had disappeared from the list.

The same situation repeated with another set of components.

By the way, when I try the same set of components but with an ASUS Z370-P motherboard, there is no problem with Windows 10 installation.

I still need to assemble some systems with Gigabyte motherboards.

Update: It was easy to install Windows 10 on the SATA SSD. Same conditions: Gigabyte motherboard, but SATA SSD instead of M2 SSD.

Any suggestion what to do in order to install Window properly?

 

Gigabyte 990FXA-UD3 (Realtek) - No bass/sub-woofer

• Speaker Setup plays all speakers fine
• Applications do not play any bass through subwoofer (or really, at all)
• Custom built PC using Gigabyte 990FXA-UD3 motherboard onboard audio.
• Windows 10 fresh install
• Tried latest driver from Gigabyte, Realtek, and Microsoft
• Windows "default" driver does play bass through sub-woofer, but audio stutters and is quiet.

Not sure what else is relevant to mention; I've tried following various posts with suggestions to fix this, with no success. I've been at this for quite a few hours and am very frustrated.

Please let me know if you have any questions, or suggestions on how to resolve

 

Losing HDD boot sector everytime I start Windows

I have a HDD with a strange behavior.

This is a data drive. Everytime I start my system, when I access this drive the first time, Windows ask me if I want to format it.

This is a typical NTFS boot sector problem, so I fix it with the backup boot copy by using "testdisk".

This happens either I plug it as an external USB or as a internal SATA drive

However this is becoming annoying and I would like to understand why. any idea?
