My experience says when the driver stops responding it means the Core is being HEAVILY overclocked. so you may try underclocking. 500 Core, 400 Mem.
Try it. If that really wont work, must be something else. Maybe incorrect voltages.
Thank you very much for your "underclock" idea! looks like it reeeleay helped!!
thank you all guys for all your productive advices!

Q: tried to update BIOS, now my videocard not working, my beautifull ATI X6660 and NVIDIA 7770 (BIOS crash):
A: you need to re-flash BIOS again! it's possible, don't worry! you can flash BIOS with this way: you must use at same time two cards - board integrated or external and your card with crashed BIOS. choose in motherboard BIOS to load from internal videocard and load to DOS. before that you need to create some little temporary FAT32 disk on your hard drive and drop there correct BIOS for your videocard and BIOS flashing tool, downloaded from
FROM HERE.
it is better to flash BIOS from DOS to avoid unexpected errors. then go to this disk and try to find crashed videocard with bios flashing tool and then re-flash BIOS again.

Q: in first minute (minutes) of gameplay card freezes \lock-ups \ crashes \ reseting e.t.c.
and \ or this error message appears:
Display driver has stoped responding and has recovered
A: Did you tried to overclock your videocard? the most frequent reason of this is CARD DAMAGE is CALLED BY OVERHEATING. to check this out try to underclock your videocard and monitor GPU clock and memory clock when testing videocard (playing wide load game). you can monitor your videocard status in fullscreen with
THIS util (read help). undercock your videocard - reduce memory and GPU clock (MHz) on 50-100 MHz. if problem persists try the minimal clock.
BE SURE THAT CLOCKS IS REALLY REDUCED by using monitoring
IN FULL SCREEN MODE programs!
