The only suspicious things happening in the report are:
- RAM usage error for Overwatch (this is generated by Windows, and is common, even when you have loads of RAM).
- Lots of crashes from Firefox.
- A crash from BTweb, which is a Web plugin from BitTorrent.
Beyond that, have you updated your chipset drivers for the CPU? Or have you checked for overheating/temperature spikes with an app like HWMonitor?
