I bought a refurbished mobo and installed it into my GX270.. Connecting the on-board VGA to my Dell 1704 monitor and it gave me a nice crisp signal and display. After a brief happy dance, I disconnected the VGA from the PC & monitor and installed the ATI Radeon 9200 256MB AGP 16X/8X/4X video card. Blank screen. I can't install the driver set without the card installed. The card box was new, unopened, and in original shrink wrap. The anti-mag bag for the card had not been opened. The driver CD was still sealed.
I tried the AGP card again. Without it, the Dell GX270 boots just fine, I get a nice display, and everything is fine. I went into Setup and made sure the video was set to automatic (my other choice was onboard). I installed the AGP card and nothing. So, is it possible that when the other mobo died it took the AGP card with it?
I installed the Radeon 9200 in my old Gigabyte K8NS Pro mobo.Other than getting a warning the drivers weren't correct, it displayed beautifully on my daughters 21" LCD. I saw one article on the Dell site suggesting the onboard graphics (Intel) be disabled in Device Manager. Might as well try it. Suggestions?
The most recent BIOS, A07, is installed. The AGP slot is an 8X/4X 1.5 volt slot per Dell. The monitor is getting a signal because the signal block that appears on the screen when the cable is disconnected. I'm getting frustrated.
I've installed a new 400 Watt PSU. I got smart and photographed at the connections before I yanked the old supply. The new one fits perfectly. There are only two power connections on the GX270 mobo, so hopefully everything will work. Now to plug it in. If the Radeon 9200 works, I can install one or two SATA drives.
Well, another chapter in this saga. When the ATI Radeon 9200 AGP 8x card is installed, the computer will not boot. When it is removed, the comp boots. Latest bios, drivers, etc. As I wrote earlier, the card works fine in another PC with AGP. Suggestions?
Solved the problem. Got rid of the ATI card and inserted an older nVidia GeForce2 MX. Works like a charm. Either the ATI card was counterfeit (misspelling on box, no UPC) or Dell & ATI don't play nice together.
