Well, I've had terrible trouble trying to install this new graphics card to replace my old nvidia 9600GT.

Old card 9600GT Nvidia

I uninstalled all of it's drivers and software (At least I think I got all of it) I turn the computer off, install the new card into the tower (Yes, it's plugged all the way in to the PCIe slot along with the additional power source) when I power the computer on, the monitor gets no signal, so, I remove the card, plug the monitor into VGA, then install the drivers given to me directly from AMD for the appropriate device.

It shows that everything was installed properly, but when I check my device manager, there is no display adapter listed, it just says: "Other Devices" --> "Video Controller (VGA Compatible)"

Something is not right obviously and I apparently have NO clue what I'm doing.

I'm hoping someone will do a team viewer session with me and help me find the problem.


tl:dr
I can't get my new gfx card installed, drivers are not installing properly, I don't think I removed all of the old drivers from nvidia (I don't know where to find them). Assistance is needed in isle 3.

"I remove the card, plug the monitor into VGA, then install the drivers given to me directly from AMD for the appropriate device"

Do NOT install drivers before the card is installed & recognized by Windows. Other than that, it's difficult to help when no specs are provided. We need to know the make/model of your motherboard (it may not be compatible with a PCIe 2.1 card) & we need to know the make/model of your power supply (or it's specs - not just wattage).

"..... I turn the computer off,...."

You MUST REMOVE the AC power to the computer, not just have the computer not running, otherwise you can DAMAGE the card's circuits, or the PCI-E X16 slot's circuits, or both.

The video card DOES NOT require any software on the hard drive while booting the computer BEFORE the operating system is loading in order to produce video from it.

Specs

Minimum System Power Requirement (W) 400W
Supplementary Power Connectors 6-pin


AMD Radeon™ HD 6770 Graphics
http://www.amd.com/us/products/desk...

System Requirements

■450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (600 Watt and two 6-pin connectors for AMD CrossFireX™ technology in dual mode).
■Certified power supplies are recommended. Refer to http://ati.amd.com/certifiedPSU for a list of Certified products

(Dual mode = two HD 6770 cards, or two HD 6770 video chipsets on one card e.g. 6770 X2.)

If you have, say, a 350 watt PS, you might be able to get away with that capacity for the 9600 GT card, but not likely for the HD 6770 card.
