Recently I was moving my computer around and I lost the signal from my graphics card (an Nvidia 7300) I assumed the card died and went out and bought another card, a ATI Fire GL V3600. This installed and worked just fine until I moved the computer, jiggled some wires (and maybe the card) and on boot up, no signal. I plugged my monitor into mobo output where I did get a signal, so the output had reverted back to the onboard GPU. So I connect back to the onboard graphics and I am once again down to one monitor.
The problems are occurring with my Gateway GT5032 PC. With a little research I learned that the Gateway GT series is notorious for this problem of not detecting items installed in the PCIe slot and hundreds if not thousands of GT owners are having the exact same problem. People are assuming dead slots, dead cards, bios issues, but no one including a very non responsive Gateway, seems to have solved this mystery.
In my trying to diagnose the GPU problem I have fiddled with the bios, and drivers and the device manager, installed the GPU in various ways, cleaned the PCIe slot, reloaded the OS, uninstalled and reinstalled drivers, etc, etc. Now, suddenly I lost use of my USB mouse and other USB devices. (by now it should be pretty obvious I have no idea what the hell I’m doing!). To fix this I started poking around in the Universal Serial Bus Controllers section of the Device Manager and learned that DISABLING the Standard Enhanced PCI to USB host controller fixed my USB problem!
So now I’m wondering if the PCIe slot problems and my USB problems are related. The gateway mobo (a Foxconn C51GU01 is just a plain stinky mobo). There is no physical way to disable embedded graphics card but you can configure the Bios to detect the PCIe slot before the embedded card.
In the properties for the Standard Enhanced PCI to USB host controller the info says it’sPCI bus 0, device 11, function 1, but under System Devices the properties for the “Nvidia nForce PCI System Management “ say that it’s “PCI bus 0, device 10, function 1”. Under Resources/Resource settings it says “This device isn’t using any resources because it has a problem”. Is there a conflicts here? What other clues should I look for to solve this problem. Help all of us Gateway GT owners fix our PCIe problems. Please!!
