Graphics Card Won't Boot

[Win]

My graphics card won't boot for some reason, it was working the night before, turned on my computer the next day and all I get is blackscreen.

I connected my VGA cable to my on-board VGA connector, and it works. I then checked if my graphics card was showing under display adaptors in device manager, but it wasn't.

Therefore, the card must not be able to boot/power up, or it would be showing.

Any suggestions are welcome.

Thanks.

If it isnt showing up, then maybe you just need to rollback the driver for the card? That or maybe install driver genius and see if maybe you need to update it?

Fixed it by plugging in a DVI to VGA adaptor. The VGA port must have broken.
