Computer wont boot up

[vallver]

Well my computer doesn't boot up once I install the ati drivers (both updated and the ones that came with the card)

my card is a X800GTO and I'm sure it is the card's fault cause I formatted like 3 times and have had the same problem



Thanks in advance

When you say the computer doesn't boot up, is it just that the screen is blank or do you think the pc's not loading up at all?

Also, have you checked if you card needs a power connection inside, and is it plugged in if that's so?

And will it run without the ATI drivers installed?

Black screen

and the card run fine until a week ago (no changes were made)

it runs perfectly without drivers
