My computer freezes seemingly randomly when playing games.

My computer freezes seemingly randomly when playing games. It's not overheating according to msi afterburner. When it crashes a loud crackling sound can be heard from the headphones. The computer is fairly new and selfbuilt. I want to know why it does this and how it can be fixed. Would appreciate any help given, thanks in advance!

This could be caused by the NVIDIA card not playing nice with MSI Afterburner. Did you recently update your NVIDIA driver? If so I would roll back to the previous driver or get rid of the MSI afterburner.
