Is there any bios's that cause problems with the r300? Im having problems and looking for the best bios to use.. maybe it will clear up my problems?

I keep locking up at a black screen just before the welcome screen.. if I boot into vga mode and try to change the res it locks up. I can get into safe mode fine, and if I uninstall the drivers I can boot normally and change the res at will (but stuck at 60hz).
