detonator XP?

Why is that when i use the detonator XP drivers ill benchmark it with 3Dmark2k1 and it'll get halfway into the first test low detail and it locks up, i'm using the first system in my signature, when i use the hercules drivers it runs fine, also this started happening after i flashed my vid cards bios, duz hercules not like anyone using the detonator drivers or is there just a problem with the new xp drivers? any help is appreciated

Since it happend right after you flashed your video card's bios, maybe something went wrong?

Actually the flash couldnt have been better, or smoother

With what bios did you flash your card? What is one from Hercules? Did that bios contain different core/mem speeds? Try flashing back to your old bios.
