Last week I was OCing my Gigabyte 4850 and I was testing for stability for several hours, anyway after everything was fine I used winflash to set the new settings. restarted and the system was NOT STABLE AT ALL!!!!!!
I tried to reverse the steps, and finally when I set it back using Winflash the PC didn't boot. Did I burn the card?
That isn't a good PSU for a Gigabyte 4850, I have one myself, and my 500W craps out if I play a game that pushes the card to 100% load.
Plugging the card into a different PC or using a different card in your PC will allow you to see what's happened. When OCing my 4850 (did it on my old 650W PSU before it died), I just used the Catalyst Control Center's ATI Overdrive tool, and to set it to default, I would just disable Overdrive again.

Flashing GPu can sometimes lead to problems, Soft mod for OC on GPu is preferable..
Try get Orig Bios and re-flash using second system..
