Dead Acer Apsire 7520g

[engineers]

Hi there,

I did a bios flash on my acer aspire 7520 G, Nvorce chipset with amd cpu

But it went bad, so my system wont boot, so i have black screen and it seems my bios is death.

I did de bios recovery on it, but it wont flash at all, it loads files on the usb floppy and stops.

Is there someone that could help me out??
