Ok, i want to help but we need to clear up a few things first, you just dont call everything 'miner crash'.
1. MINER CRASH
Miner window closed, or windows returned a message the app crashed, or miner just quit and all you got in the cmd window is a "press any key to continue message". Basically miner isnt running anymore.
2. VIDEO DRIVER CRASH
When miner is reacting to keypress, but hashing with 0 hs. Also if you had a message from os saying the driver crashed, or stopped responding. Win10 says graphic hardware is blocked. This is not 1 (miner crash), it means you should check your OC settings mainly, or lower intensity in miner.
miner not crash directly. no stop. no error.
one trouble freeze and dont hash on pool and no messages localy. driver not crash too. any key show on window and dont show rate and pool\miner info. close window and restart work fine same time.
second trouble. miner work and reinit card without error. cyclic reinit and dont calc until close\reopen
both trouble on different rig. 1.7.8 work without this trouble
