the game crashes by the time the level loads..

[Puchatek]

i installed king's bounty PL and applied official Cenega Poland 1.6.5 patch including 1.7 changes.. i started the game, i ran it on recommended default video options and 5 secs after loading... the pc restarted.. the game was running smoothly, no malfunctioning.. graphics was ok and fps was good.. so i decided to lower graphics settings to minimum.. the same.. i installed latest ATI Catalyst.. now the pc crashes RIGHT after loading, it doesnt wait even 5 seconds.. the game was visible for... 0.3 seconds? it's weird.. i thought hat maybe i have too weak graphics card, but no.. in these 5 seconds game was running smoothly, i could rotate the camera without any problems, no texture, model corruptions.. everything was ok.. but keeped restarting.. only plying KB results in such way.. any ideas?

my card is RADEON 9600 PRO 256M AGP, and processor is Athlon XP 2700+, 2G RAM.. the game default settings is 1280x1024, normal texture details, and high water appearance.. so it dont seem to be graphics problem..

i know, it's ancient device, but i stated it.. the game was running perfectly, but it was lasting 5-7 seconds until restart.. i could move my character, go to hero window.. and then restart.. menu works perfectly, i have got saves from other computer with KB installed, and there are no problems.. i thougght that maybe the save makes problems, but no.. any new game started behaves in identical way.. i bought King's Bounty: Legenda Edycja Kolekcjonerska (Collector's Edition), it is no cracked or ripped version.. help me, please.. i think i tried everything.. adjusting the card in catalyst control center.. i;m fed up with it..
