Why is my 8600GT after a BIOS flash give me a blank screen?

Question

the gfx works in my other computer though but not in my dell. U used a separate moniter for my other computer so the problem may be the moniter or the DELL computer. Please relpy. Im on the verge of breaking the GFX in rage lol

Answer 1

Perhaps Dell power supply is small and does not have enough juice for the 8600GT which draws almost 50 watts.
