Random BSOD

[Nodulariny]

Hello,
Recently I built a new gaming computer and have been experiencing random BSOD. I am unsure what is causing these BSOD because I am not super tech savvy...I understand the parts but not so much the program side of the computer. I have ran Memtest for 8 passes and no memory errors were found. Bios and drivers are up to date as far as I know, but I could be mistaken. BSOD occurs when running steam, watching twitch, playing games, ect. WhoCrashed has linked it consistently to ntoskernl.exe but after looking up that on the internet I was unable to find anything so I was hoping someone on here could help me.
Any help would be much appreciated.
Thanks you.

Hi Nodulariny.

Uninstall AVG using AVG Remover. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.

Let us know for any further BSOD after doing it. Also let us see the link wherefrom you got the memtest tool. Because there are two programs with deceptively similar names, and one of them is just a crap.
