Hello. I tried to update bios for my new graphic card, i used bootalbe pendrive with atiflash + some bios for HD 4870 ( i think i chose wrong bios, but i;m not sure), when i type atiflash -f -p 0 4870.bin there was some text and at the end "now u can restart ur computer" something like that, then i used ctr + alt + delete. After reboot my monitor was OFF GPU fan was ON and nothing else. I took my card to my friend who have 2 x pci-e for first slot we put his 8800 and for second mine card, then i boot again winflash from USB stick, and when i used winflash -i, program saw only 1 card- 8800... when he lunch his OS in new drivers it was new device without drivers, so i;m sure OS saw my card... What can i do before use guaranty(time=3-4 weeks)? At the end for my post sorry for my english ;p please reply someone with some advice.
