Just purchased a bricked card very cheaply with the seller saying the fan spins but no signal to the monitor, in case it would work in my PC. PN 299-IE207-000SA Model here When I got the card it did the same thing (on both bios switch settings) so switched to onboard gfx and force-flashed a few bioses (biosi?). The closest match was the 810mhz sapphire on this site but it didn't work. I finally got it to work with the Flex dual X bios posted by Techtu in this thread, and was delighted! However after working fine for a day or so (including gaming tests) at decent temps, the card showed the old symptoms again and now refuses to send a signal after further bios reflashing. I'm now guessing the card is faulty - if I rule out my m/b & psu because it did the same thing with the previous owner, plus the fact that bios 2 doesn't work.... but if anybody has any suggestions or more bios's to try I'd very much appreciate your help! I almost wish it hadn't worked at all...I think it's taunting me!
