Ok so I will put a mash of PROBLEMS that I have, as I will copy and paste this on SEVERAL forums (I'm going desperate, need help soon).

1. Recently I bought a 220gt. Now my old card was a 120, and after installing driveres and everything (on displayh settings, it shows gt 120 for example it says displaying at 800x600 on gt220) for some reason I am getting WORSE performance on games than before. I heard it was supposed to be loud, I cant hear it, I checked the card for a 8pin connector for power but found none, is there one?
On a quick note that has me worried, while playing dead space, I was playing fine when my computer blacked out. The computer was still on but the screen said No VGA detected, what the *censored* hapened?

2. Me ethernet drivers have stopped working, I think this was shortly before I removed the Nvidia drivers from my computer (I removed all Nvidia drivers) either way, I ahve TRIED everything and it is not working. When I go to the device manager, here are the things that are not working:
Coprocessor (under storage devices)
Ethernet Controller
SM Bus controller (both under other devices)

My computer is the gateway lx6810

Please help me!
ThxSomebody will be with you shortly. It is hard for me to offer much help.
I am not SURE you can put that card into the stock gateway PC. It would be helpful it you would include some specs on your machine so we don't have to look it up. Like what is the Power Supply on you Gateway? Did you upgrade it? Did the documentation with the 220 video card say you need an extra power connector? I could look that up, bit that is the kind of homework you are supposed to do before you even buy the card.
Here is what you might have done.

1. You may have overloaded the power supply.
2. You may have damaged the video card by forcing it to run the wrong way.
3, Something else so bad I don't even what to guess. Quote
