May have solved Random crash fix

well game was crashing every 10mins but now played for about 40mins no crash... What i did was Turn off steam ingame overlay. Also i increased my voltage to my cpu by .2 (im guessing its steam overlay though)

If it still crashes, make sure you install the directX redistributable and vcredist that came with your download from steam. They're in steamapps\common\Fallout 4\_CommonRedist.
