Recovering Bricked HD 6850 Video Card

After flashing the bios of HD 6850 to 6890, it had requested for the restart, but afterwards, it just shows a black screen.

I have HP H81050 PC and it has Integrated Graphics, which I only can use to see anything on monitor, ONLY if the HD 6850 video card is either unplugged or uninstalled - otherwise just a black screen.

I have tried flashing the original version of the bios, but the video card needs to be plugged in, in order for “atiflash” (USB boot) to detect it or it just says “adaptor not found”!

A forum post suggested that plugging in while in windows and then scanning for new hardware changes would allow it to detect the card, but then it would need to be restarted, otherwise, it just says “not enough free resources for it to use” with the yellow hazard mark. It was suggested that the video card would then “POST” after rebooting from the window, but then again, it just shows a black screen. I have also tried to plug in as soon as the computer turns on and shows the motherboard’s bios version, but still the same results in windows and when booted through USB.

I was looking for 1 & 8 pins method, but can’t seem to find the power chip on the video card. There are two of them. (VHCT125APQUX & uP7701u8CGP14B) And not sure if they are needed at all - this method...

I know the video card works(as it was detected in windows), but needs to find a way to make it work with the computer, so I can flash the original BIOS.

P.S. - The video card doesn’t have any BIOS switch.

I’d appreciate any help, thanks.
