if the graphic card (SAPPHIRE HD 6870 1GB GDDR5 Vapor-X) is activated my computer show a blue screen and does not start in normal mode.
If the graphic card is NOT activated, my computer starts with low resolution.
I tried to uninstall the last drivers downloaded on your web site and to re-install them but same troubles.
I do not have serial number neither bios version because I asked a friend of mine to have a look at the computer.
What could be the reason of the troubles ?
Thanks for your quick reply.
I am lost without my computer.
