I recently a second graphic card so i can crossfire them, but my second card seems to show lines over the main image from the point of turning it on, when i first used the card it did work good for a little bit only for a few mins since needed other parts(dvi to vga) to run both.
It happens weither i run only on card or both, I have also made sure it has enough power, I don't bother running it up to windows starts since the bio's screen shows the lines.
Any one have any idea whats wrong?
All my monitors work good same with dvi to vga converter.
