The screen was in 800-600 resolution at bios and the screen was fairly pixelated with also pixelated blocks. The pixelated blocks had a mix of yellow, red and white colours. It then loads at windows logo and then bluescreens shortly after. The card i think is now officially broken.

I'm pretty sure i voided the warranty.

Tried it in my brother's setup and same thing, can't load into windows so it cant even be configured in anyway.

Don't even know what to do...

Use DOS mode to reflash that card with your original bios. Your getting artifacts because your card isn't accepting that bios. Your card is fine. It just needs it's old bios back. Do it from DOS before booting into windows. I've done it a million times smile.gif

Mine does the same thing. When I first unlocked BIOS it went up to 145%, but now it rarely goes over 110%, sometimes during game it goes to 112%. So I'm curious for an answer too.

Clocks at 1215Mhz on unlocked BIOS. Nothing special.

Mine used to not go past 108%, now it goes slightly higher to 112%, but usually below 110%. I took it as it didn't need that much power.
