I have a Nvidia GeForce 6600 PCI-E 256MB graphics card that i just got, but my Windows 7 Home Premium x86 on my Dell GX280 desktop computer isn't working with it. It shows up in Windows device manager but won't let me download the drivers from there. I go to the Nvidia site and download the driver and it says that it doesn't detect any graphics hardware. What do i do?

The best card you can safely run on a 250 Watt PSU is the Radeon HD 5570. It is a DX11 card, so it can also do DX10, it's more powerful than any of the 6600 series nvidia cards, though it's not exactly a powerful card by today's standards. However, most cards more powerful than the 5570 would probably be bottlenecked by your CPU. Edit: I might be wary of running a 5570 on that 250 Watt, capacitor aging has probably reduced that old PSU's capabilities, you may need a new PSU either way.

Your motherboard should not care how large a power supply you have. The only recommendations I see in mobo manuals are the minimum PSU you should have for a system, and usually they recommend a 300 Watt to be on the safe side, even if you are only using...

Im tech savy, but not when it comes to terms. Dumb that down for me a little please. And the only detachable connection on my version is from the fan to a connector on a lower part on the graphics card. There is a picture of it on this link: http://www.newegg.com/Product/Product.aspx?Item=N82E16814130260

The manual download checks for the hardware too while it is installing and doesn't find it so won't finish install, yet it still shows in the Windows 7 device manager. And it is 32-bit Dell Optiplex GX280 2004 Desktop Tower Version with a single 3.6ghz processor and 4GB RAM.

I will soon, but first i discovered it may be the fact that my computer has a 250 watt psu and my motherboard doesn't recomend more then a 305 watt psu. That is probally too low for any good gpu. Any suggestions for a DirectX 10 quality gpu that works with a 250 watt psu and is on the cheaper side of things, but still good quality?

Your motherboard should not care how large a power supply you have. The only recommendations I see in mobo manuals are the minimum PSU you should have for a system, and usually they recommend a 300 Watt to be on the safe side, even if you are only using integrated graphics. There should be no reason for your motherboard to restrict PSU size, unless this is one of the Dell's that has proprietary power connectors, and as such will only take certain Dell PSUs.
