Twice in a few days I've found my PC blue screened. It has crashed while I've been away from it, just idling with firefox open. Don't know if that has something to do with it, memory leak in firefox or something. But anyway, here's the 2 blue screens and crash dumps, if someone who understands anything about them could take a look and maybe shed some light on the cause. Would be much appreciated.
Ok, I have just updated BIOS and (re)installed network drivers and all the other drivers found from the gigabyte website. There's no newer driver for my mouse available (Razer Copperhead).
Hopefully that'll fix the blue screens. Thank you for your help.
