Re: game crashes for no reason
Updating my BIOS fixed random crashes and freezes and restarts.
I've got a fairly new mobo, but found that two new versions of BIOS was available - both of them promised "increased system stability" - so I flashed my BIOS with the latest update.
Never had a crash since (two days now) - that is when playing on High.
Tried Ultra (recommended nvidia-settings) but could only play for a "good while" before freezeing (with and without ambient occlusion).
(If any of you want to try this - remember the USB flash needs to be formatted in FAT32)
