BSOD or Freeze. Replaced RAM ran MEMCHECK OK

[C3H5N3O9]

Hey, I've gotten the occasional freeze or BSOD. Often times during a movie, but not exclusively.

I ran memcheck all day and no errors and I've also replaced RAM.

I'm thinking something related to heat, but I'm not sure.

Thanks for the help!

Crashes indicate Avira being a possible cause. Remove Avira and replace with Microsoft Security Essentials to see if it provides more stability. Uninstallers (removal tools) for common antivirus software. Microsoft Security Essentials and Malwarebytes are recommended from a strict BSOD perspective. They do not cause blue screens on the system as other AV products do.
