i am having a very weird problem with my Gigabyte Radeon 9000 64MB DDR , the original freq. is 250 core - 400 mem.when i try to overclock or even underclock it just a little bit (2 MHz only) the PC restart!!.
i used many utilities like V-Tuner, Radeonator 2, Rage 3d Tweak & Power Strip; and they all gave the same problem(restarting).
i guessed that there is some kind of protection in the BIOS of Gigabyte to prevent Overclocking, so i thought of flashing a new BIOS from other brands that make the same card like FIC or Powercolor, but am afraid that it can cause a seriouse problem and rune the card
so if anybody know anything about this problem plz helpme and if anyone try before flashing the BIOS of a VGA card with no problems plz tell me
