Guide to Video BIOS flashing
ATI: WindowsTo flash your BIOS from within Windows you have to use the ATI Winflash Utility, find it in our downloads section.
The interface is pretty straightforward - load the BIOS image, click on program. Done.
Try closing as many programs as possible before the flash. It wouldn't be too good for your video card if your MP3 playing software messed up something with the sound card driver which displays a bluescreen and then halts the whole system.
