After getting my Dell I decided to update to the latest nVidia driver, which at the time was released 3/14/05. For about 2-3 weeks everything was fine, then I began getting horrible frame rates in CS:S, usually around 15-20 fps. So I updated to the latest nVidia released drivers, 71.89 (4/18/05).
I rebooted after updating to the new driver, after I got to the Windows XP load up screen it went blank and the screen turned off (as if not to receive a video signal). After about 15 seconds it shoots to a blue screen, memory dump with the error from a file called nv4_disp. This is obviously an nVidia file from the driver. After rebooting again it went to a screen with vertical lines, blue/white at first and then changed to gold/white.
I tried going into Safe Mode and rolling back the driver, no cigar. Uninstalled the current 71.89 driver and reinstalled the last one, same problem. Then I tried reverting back to the Dell.com supported drivers from 1/21/05. The driver is specific to my nVidia 6800 GTO 256 PCI-X card. On installation it gave an error "nVidia setup unable to locate driver compatible with your video card. Setup will now exit".
So now I'm stuck in VGA mode in Windows XP, driverless. Nothing is working. The only thing that would make sense is if the BIOS on the vid card was flashed when installing to the 71.89 driver set. I haven't been able to find documentation of this anywhere. The card should be working fine, haven't had issues of sudden power loss nor anything regarding heat issues.
Dell support is no help. At the end of the 1 hour phone sessions they said that the card that was currently installed is not compatible with my Dimension 8400. I advised them that it was the card that came with the computer........ GG Dell.
They advised they would get back to me in about 2 hours after I gave a huge shpeel about how the problem must be physical. I'm not sure about this however, because I'm leaning more toward the possibility of the card being flashed during the last update to the driver.
Please help me someone, I'm disturbed! My current comp configuration is as follows:
Intel Pentium 4 630 w/ 2mb L2 cache (LGA775) (3.0 GHz)
Dell Mainboard (Intel i925X Rev. B1 chipset) Dell BIOS A05 (most up to date)
512 mb DDR2-SDRAM
Dell nVidia 6800 GTO 256mb PCI-X (71.89 drvr) Device ID=PCI\VEN_10DE&DEV_00F9&SUBSYS_00000000&REV_A2\4& 16EC1A1&0&0008
I hope that helps.
