  1. Hey, I recently bought an XFX HD 6870 (upgrading from a 9800 GX2) and the computer boots fans are all on but once it gets past the bios the monitor looses signal. I also upgraded windows vista to windows 7(clean install) and can not enter into safe mode because the screen goes blank. If i put my old graphics card in the card works perfectly. I have reseted the cmos and sent the card back to the suppliers finding no faults in the card.

    Thanks for the reply, i found the solution, the graphics card couldnt detect the monitor because of the adapter i was using.
