Install a New Video Card in Your HP Pavilion 6630

On HP Pavilion 6630s, you cannot disable the onboard graphics in the BIOS setup. But here's another way.

Steps

Log on in safe mode, whilst your computer is booting up press F8 repeatedly, you should get a listing of boot options, select Safe Mode.
Once you are in safe mode and logged on as the administrator, right click on My Computer, then select properties.
Once in properties, select the Hardware tab.
Click on the Device Manager button.
Click on the + sign by your display adapters.
Right click on the onboard graphics controller, and select disable, not install. This will only cause a world of misery and woe.
Log off and turn your computer off.
Crack her open, and install your new graphics card.
Plug everything back up, and close up the case, turn your computer back on.
Once you log in it should say "I found new hardware, gimme a disk,".

Unplug everything, especially the main plug to the PSU (Power supply unit).
If you live in the UK or have a rocker switch, leave your computer plugged in but the rocker switch off-It will keep the computer grounded.
Use a grounding wire, you don't want to fry anything now...

When working with computers, there's always a risk of electric shock, be careful
