Hd 7750 bricked on dell optiplex 745 due to flashing

So I, like the idiot I am, used winflashati to flash my Radeon hd 7750 graphics card with a new bios. I made a backup. In the middle, it says it has successfully been flashed. Then my screen freezes and I sit there for 10 min. Then hold down the power button and try to reboot. There is no signal and I can use the vga cable to use my igp graphics but when I have the card plugged in at the same time, it says unsupported video configuration so I can’t post using igpu while the graphics card is plugged in. I have a usb but not a pci card. I don’t think I’m able to flash this card using my igpu and at this point I’m desperate for help. Any solution would be appreciated

Reported as being posted in the incorrect section, hopefully a helpful Mod can move it to the GPU section.

Not much you can do then (won't post = no blind flashing possible). Unless you can borrow a friend's PC or send the card to someone willing to flash it for you.
